Minor changes to SWC plugin telemetry payload. SWC's plugin can be either resolvable npm pkg, or absolute path. If it's an absolute path, try to grab actual plugin name only as we do not need any paths.

In certain cases, mini-css-extractor will create independent `CSSModule` to the module graph, which doesn't have a user request or resource. Hence we can't match them in the flight manifest plugin like before. This PR adds a work around to use `mod.type` and `mod._identifier` to get such CSS assets.

This PR introduces an environment variable that allows to modify the `EdgeRuntime` value on compilation time.
This is done to allow cloud providers like Vercel to have a different value, and enable user code and 3rd party libraries to have different code paths depending on the Edge Functions provider.

# Description
Hi guys! First all, thanks for provide a way to use some custom external cache resource for ISR feature. _(done here: https://github.com/vercel/next.js/pull/37258 and https://github.com/vercel/next.js/pull/37326)_
I managed to get it working by creating my custom external cache resource _(using redis)_ that implements the new `CacheHandler`. _(overriding my own `get` and `set` methods and using the FileSystemCache as fallback as well)_
I'm planning to release some kind of plugin to encapsulate and parse the client's `next.config.js` and bring an initial support for redis using this new Next.js feature.
So, I really don't know if this was intentional, but I noticed that the new `incrementalCacheHandlerPath` prop wasn't passed to the `IncrementalCache` instance in `base-server`.
This PR just connects the wires for this feature, and also provide the default value (`undefined`) to the relative experimental prop config. _(to avoid the warnings as shown below)_

This outputs a separate manifest for leveraging during deploy to handle the new app outputs. Also ensures dynamic routes from `app` our output in the `routes-manifest` correctly along with fixing the `react-dom` import.
x-ref: https://github.com/vercel/next.js/pull/37551
This is second attempt to https://github.com/vercel/next.js/pull/38076 . Most of changes are identical to previous PR. Main difference is introducing features `native-tls` and `rustls` for the sentry's downstream feature. Few platform targets we build (mostly where we cross compiles) fails to find native openssl for the specified target. For those, we falls back to rustls instead. The only exception is aarch64_windows, neither openssl nor rustls can be compiled straightforwardly, For those platform we bail out and do not init sentry at all. There are nearly 0 users on aarch64_windows anyway. We could try to located target's openssl binary, but the effort required seems not worth enough.
Also PR changed `server_name` property to not to include real device hostname to avoid possible PII concerns.

## Client-side router for `app` directory
This PR implements the new router that leverages React 18 concurrent features like Suspense and startTransition.
It also integrates with React Server Components and builds on top of it to allow server-centric routing that only renders the part of the page that has to change.
It's one of the pieces of the implementation of https://nextjs.org/blog/layouts-rfc.
## Details
I'm going to document the differences with the current router here (will be reworked for the upgrade guide)
### Client-side cache
In the current router we have an in-memory cache for getStaticProps data so that if you prefetch and then navigate to a route that has been prefetched it'll be near-instant. For getServerSideProps the behavior is different, any navigation to a page with getServerSideProps fetches the data again.
In the new model the cache is a fundamental piece, it's more granular than at the page level and is set up to ensure consistency across concurrent renders. It can also be invalidated at any level.
#### Push/Replace (also applies to next/link)
The new router still has a `router.push` / `router.replace` method.
There are a few differences in how it works though:
- It only takes `href` as an argument, historically you had to provide `href` (the page path) and `as` (the actual url path) to do dynamic routing. In later versions of Next.js this is no longer required and in the majority of cases `as` was no longer needed. In the new router there's no way to reason about `href` vs `as` because there is no notion of "pages" in the browser.
- Both methods now use `startTransition`, you can wrap these in your own `startTransition` to get `isPending`
- The push/replace support concurrent rendering. When a render is bailed by clicking a different link to navigate to a completely different page that still works and doesn't cause race conditions.
- Support for optimistic loading states when navigating
##### Hard/Soft push/replace
Because of the client-side cache being reworked this now allows us to cover two cases: hard push and soft push.
The main difference between the two is if the cache is reused while navigating. The default for `next/link` is a `hard` push which means that the part of the cache affected by the navigation will be invalidated, e.g. if you already navigated to `/dashboard` and you `router.push('/dashboard')` again it'll get the latest version. This is similar to the existing `getServerSideProps` handling.
In case of a soft push (API to be defined but for testing added `router.softPush('/')`) it'll reuse the existing cache and not invalidate parts that are already filled in. In practice this means it's more like the `getStaticProps` client-side navigation because it does not fetch on navigation except if a part of the page is missing.
#### Back/Forward navigation
Back and Forward navigation ([popstate](https://developer.mozilla.org/en-US/docs/Web/API/Window/popstate_event)) are always handled as a soft navigation, meaning that the cache is reused, this ensures back/forward navigation is near-instant when it's in the client-side cache. This will also allow back/forward navigation to be a high priority update instead of a transition as it is based on user interaction. Note: in this PR it still uses `startTransition` as there's no way to handle the high priority update suspending which happens in case of missing data in the cache. We're working with the React team on a solution for this particular case.
### Layouts
Note: this section assumes you've read [The layouts RFC](https://nextjs.org/blog/layouts-rfc) and [React Server Components RFC](https://reactjs.org/blog/2020/12/21/data-fetching-with-react-server-components.html)
React Server Components rendering leverages the Flight streaming mechanism in React 18, this allows sending a serializable representation of the rendered React tree on the server to the browser, the client-side React can use this serialized representation to render components client-side without the JavaScript being sent to the browser. This is one of the building blocks of Server Components. This allows a bunch of interesting features but for now I'll keep it to how it affects layouts.
When you have a `app/dashboard/layout.js` and `app/dashboard/page.js` the page will render as children of the layout, when you add another page like `app/dashboard/integrations/page.js` that page falls under the dashboard layout as well. When client-side navigating the new router automatically figures out if the page you're navigating to can be a smaller render than the whole page, in this case `app/dashboard/page.js` and `app/dashboard/integrations/page.js` share the `app/dashboard/layout.js` so instead of rendering the whole page we render below the layout component, this means the layout itself does not get re-rendered, the layout's `getServerSideProps` would not be called, and the Flight response would only hold the result of `app/dashboard/integrations/page.js`, effectively giving you the smallest patch for the UI.
---
Note: the commits in this PR were mostly work in progress to ensure it wasn't lost along the way. The implementation was reworked a bunch of times to where it is now.

## What's in there?
The Edge runtime [does not support Node.js modules](https://edge-runtime.vercel.app/features/available-apis#unsupported-apis).
When building Next.js application, we currently fail the build when detecting node.js module imported from middleware.
This is an blocker for using code that is conditionally loading node.js modules (based on platform/env detection), as @cramforce reported.
This PR implements a new strategy where:
- we can build such middleware/Edge API route code **with a warning**
- we fail at run time, with graceful errors in dev (console & react-dev-overlay error)
- we fail at run time, with console errors in production
## How to test?
All cases are covered with integration tests.
To try them live, create a simple app with a page, a `middleware.js` file and a `pages/api/route.js`file.
Here are iconic examples:
### node.js modules
```js
// middleware.js
import { NextResponse } from 'next/server'
// static
import { basename } from 'path'
export default async function middleware() {
// dynamic
const { basename } = await import('path')
basename()
return NextResponse.next()
}
export const config = { matcher: '/' }
```
```js
// pags/api/route.js
// static
import { isAbsolute } from 'path'
export default async function handle() {
// dynamic
const { isAbsolute } = await import('path')
return Response.json({ useNodeModule: isAbsolute('/test') })
}
export const config = { runtime: 'experimental-edge' }
```

## Notes to reviewers
The strategy to implement this feature is to leverages webpack [externals](https://webpack.js.org/configuration/externals/#externals) and run a global `__unsupported_module()` function when using a node.js module from edge function's code.
For the record, I tried using [webpack resolve.fallback](https://webpack.js.org/configuration/resolve/#resolvefallback) and [Webpack.IgnorePlugin](https://webpack.js.org/plugins/ignore-plugin/) but they do not allow throwing proper errors at runtime that would contain the loaded module name for reporting.
`__unsupported_module()` is defined in `EdgeRuntime`, and returns a proxy that's throw on use (whether it's property access, function call, new operator... synchronous & promise-based styles).
However there's an issue with error reporting: webpack does not includes the import lines in the generated sourcemaps, preventing from displaying useful errors.
I extended our middleware-plugin to supplement the sourcemaps (when analyzing edge function code, it saves which module is imported from which file, together with line/column/source)
The react-dev-overlay was adapted to look for this additional information when the caught error relates to modules, instead of looking at sourcemaps.
I removed the previous mechanism (built by @nkzawa ) which caught webpack errors at built time to change the displayed error message (files `next/build/index.js`, `next/build/utils.ts` and `wellknown-errors-plugin`)
since we no longer have a single compiler for browser & edge, we can enable
source map generation by default for all edge functions. This would make it
much easier to debug and understand what's happening when deploying to prod
as the log statements will show us the actual code location instead of post
bundling and minified location.
This also removes the experimental flag as it's not needed anymore.
Client components might result in a page chunk or a standalone splitted chunk marked in flight manifest, this PR filters out the page chunk for standalone chunk so that while loading a client chunk (like for `next/link`) it won't load the page chunk to break the hydration. `chunk.ids` is not enough for getting required chunks, so we get the chunks from chunk group then filter the required ones.
tests: Re-enable few previous rsc tests
chore: refactor few webpack api usage

When an API route is detected for the `getRouteInfo` method (a route with a `/api` prefix), we should redirect the user to the original destination instead of the rewritten destination. This makes the behaviour consistent with how rewrites have been documented thus far.
The reproduction described in #37783 now causes an invariant violation error (for redirecting to the same URL), but this is instead related to the fact that the router (when rehydrated) attempts to redirect the user again to the correct destination. This should be corrected either in this PR or in a future one that addresses the hydration behaviour directly.
## Bug
- Related to #37783
- Related to #37949
## Example
With the following `next.config.js`:
```js
/** @type {import('next').NextConfig} */
const nextConfig = {
reactStrictMode: true,
async rewrites() {
return {
beforeFiles: [
{
source: '/:path(.*)',
has: [{ type: 'query', key: 'json', value: 'true' }],
destination: '/api/json?from=:path',
},
],
}
},
}
module.exports = nextConfig
```
The following link:
```jsx
<Link href="/not/real?json=true">
<a>Take me to JSON</a>
</Link>
```
When clicked, will navigate the user to `/not/real?json=true` and have it's contents served by `/api/json` and not simply redirected to `/api/json` which is incorrect.

this is a regression from the previous implementation where Next.js compiled Middleware using
the client compiler. We used to favor the browser exports over the `module` and `main`,
which allowed packages like `debug` to work without any changes on Edge Functions. This is
no longer the case, and this commit fixes that.
Side note: I believe that in the future we will also have a different key to symbolize edge
deployments. Maybe it will be `winter` to refer to WinterCG, but only time will tell!
Another side note: we need to add support for import maps for advanced use cases.

Previously we use custom webpack alias for specific react versions for non server side node runtime aliases. This PR alias the entire folders of `react/` and `react-dom/` so that no more alias in next.config is required but only the nodejs require hook.
* Alias `react` and `react-dom` by default
* Use `react@experimental` to run server components integration test
* Drop with-react-17 test util, add `__NEXT_REACT_CHANNEL` as an env var for testing and development to specify the react channel is 17 or new experimental version
* Requires prerequisite PR https://github.com/vercel/next-telemetry/pull/84
This PR adds telemetry to send list of the experimental swc plugins from next.config.js. Implementation largely mimics existing plugins telemetry for next_package (https://github.com/vercel/next.js/blob/canary/packages/next/telemetry/events/plugins.ts), with small modification to read swc plugin package instead.
One notable difference is swc plugin telemetry can be sent without version. This is due to swc plugins can be specified with absolute path without any npm pkg resolutions.

This ensures we properly alias and internalize `@swc/helpers` so that we don't rely on package managers hoisting this dependency for the build to work properly. This also disables the external helpers with `jest` as this can also require hoisting to work and doesn't provide as much of an optimization.

Fixes#38106.
Currently, the `shared/lib` directory (**which will also be shipped to legacy browsers**) is precompiled under `swcServerOptions`, which targets Node.js 12 and is way too modern:
- The public class field syntax is only supported since Chrome 72, Firefox 69, Edge 79, and Safari 14.1.
- Webpack currently doesn't support the public class field syntax as well (which causes the issue #38106)
- `async/await` syntax is also supported in Node.js 12 but not in the legacy browsers.
The PR fixes the issue by pre-compiling the `shared/lib` directory using `swcClientOptions` (which targets the ES5).
Note:
- The only way to validate the fix is to run an integration test case on a legacy browser.
- The output size is increased by a little. But the size impact can be minimized by enabling `@swc/helpers` (which I will bring up in the next PR)
This PR fixes the case when `next/future/image` is missing the width or height props.
It also fixes a case when `100%` or `100vh` were incorrectly parsed as `100` pixels.
This ensures we create any nested folders necessary when setting initial ISR cache entries with the filesystem cache. Also adds a regression test for this.

This PR attempts to setup native crash reporter for `next-swc`. Currently, it uses sentry internally, but it is subject to change depending on the usecase & needs. In any case it won't be breaking changes since this is not transparent to the end users.
PR sets up basic, minimal setup to collect crash reports only at the moment. We may want to expand & collect more data in native next-swc, but it is not clear what we need to collect / and I believe most cases next.js's js context can collect those data via existing telemetry. Crash report is an exception native handler can perform much better by having it in native context directly. While this is sent to different endpoint than telemetry, it is considered as same opt-in configuration. If telemetry is disabled, crash reporter won't collect as well.
The information collected by the reporter is minimally configured by sentry's sdk. These are the informations collected for example:
- device arch / family / model
- os kernel version / name / version
- runtime (rust) version / channel
- sentry sdk
- panic backtrace
- next.js release version
- device host name
There's no per-system uuid configurations yet.
It may need some audit if we need to omit some data included in above, while most of them seems ok to me.

Minor fix to recent experimental configs. While the latest next.js includes support for those experimental features, currently it emits warnings like
```
You have defined experimental feature (swcPlugins) in next.config.js that does not exist in this version of Next.js
```
As validation checks the existence of default values even though config itself allows them to be optional. PR does not attempt to change validation logics, only amends it by having empty default values.

We don't need to include `<noscript>` for `next/future/image` since it uses native lazy loading instead of the `IntersectionObserver` (https://github.com/vercel/next.js/pull/37927).
The only case when we still need `<noscript>` is for `placeholder="blur"` because it requires client-side JS to switch the from blur image to final image on load.
avoid fetching a chunk for api endpoints on middleware redirect.
This still makes a request to the data endpoint, not sure if this is a good idea,
but a rewrite _can_ happen from that data request.

This PR introduces a new experimental component, `next/future/image`, which is inspired by the existing experimental `layout="raw"`.
The difference is that much of the code has been deleted in order to reduce client-side code as well as reduce complexity:
- No `layout` prop
- No `loader` config (although `loader` prop works)
- No `IntersectionObserver`, use native `loading="lazy"`
- No `lazyBoundary`
- No `lazyRoot`
- No `fill` (yet) so width & height are required
- No `objectFit` (use `style` instead)
- No `objectPosition` (use `style` instead)
This improves performance because native `loading="lazy"` doesn't need to wait for React Hydration and client-side JS.
In a future PR, we will modify `next/image` to remove `layout="raw"` since this new component supersedes it.

This allows configuring / overriding the default options of the `styled-components` swc transform and allows using the `css` prop support, which was already implemented, but not available.
Edit: made the CSS prop transform run before the display name, so it gets picked up by that and receives the (deterministic) name.

Hello,
This PR sorts paths array before generating `_ssgManifest.js` to keep output of static HTML exports uniform.
Before this change, the output of `_ssgManifest.js` would almost always change, which in result changes the static HTML export artifact's checksum every time.
Lately, `Response.json` was introduced as a standard static method.
That means we can remove our implementation of `NextResponse.json` piggyback on `Response.json`

This ensures we expose the `styled-jsx` types correctly even when the package is not hoisted from next's `node_modules` e.g. when using `pnpm`. We had an existing test that covered this although it installed `styled-jsx` at the top-level as a workaround so the test has been updated to remove this workaround.

* Dropping middleware related code for edge SSR: removing client info and preflight request handling
As noticed in https://github.com/vercel/next.js/pull/37596 it seems we aren't locking the `next-server` tracing to the tracing root which can allow files outside of the folder to be included unexpectedly.

When generating the RegExp for middleware using the `matcher` option we are not taking into consideration i18n and basePath. In this PR we include them always which should we the middleware default. In a followup PR we will provide an option to opt-out in the same way we do with rewrites and redirects defined from Next.js config.
This adds a guard for whenever we do a hard navigation over a client-navigation to ensure we aren't redirecting to the same URL that we are currently on as this can cause infinite redirecting. This also fixes some cases with middleware rewrites without i18n enabled and expands our middleware suite to test both with i18n and without.
This also fixes a race condition with the query updating where a user could attempt a route transition and it then gets overridden by the query updating and prevents firing router events during the query updating as these can be false signals of a transition.

If you end up in a state where an error happened and you also should be warned about a full refresh - you get stuck. The full refresh is blocked by the warning but the error is shown instead.
Tests didn't catch this because the refresh warning never showed in `__NEXT_TEST_MODE`.

<!--
Thanks for opening a PR! Your contribution is much appreciated.
In order to make sure your PR is handled as smoothly as possible we request that you follow the checklist sections below.
Choose the right checklist for the change that you're making:
-->
```js
// next.config.js
module.exports = {
experimental: {
legacyBrowsers: false,
sharedPool: true,
newNextLinkBehavior: false
}
}
```
With the current implementation, using the config above will warn the usage of experimental features. However, those are the preset values that are defined in `defaultConfig` which means actually no experimental feature has been enabled at all.
The PR changes to only check if experimental features are actually enabled (have different values than the ones defined in `defaultConfig`).
This PR switches to using an SVG filter for blurring placeholder images, rather than a CSS filter. It's based on the technique described in @cramforce's [blog post](https://www.industrialempathy.com/posts/image-optimizations/#blurry-placeholder).
One change I made to @cramforce's version was to increase the stdDeviation property of the SVG (which controls the gaussian blur strength) from .5 to 50. Smaller values than this tended to look bad, as our technique for generating the blurry placeholder image tends to produce images with sharp contrast between the pixels, which looks bad when blown up unless it's blurred by a substantial amount.
This PR currently only affects the experimental `layout="raw"` but I expect to eventually apply it to all images. CC: @styfle @kara
### What's in there?
This is a followup of https://github.com/vercel/next.js/pull/37695.
For the dev server to clean stacktraces, we're decorating errors caught during code evaluation (`getServerSideProps` or middleware).
However, when these errors are asynchronously raised, we can't decorate them before processing them, leading to this fallback logic:
bf7bf8217f/packages/next/server/dev/next-dev-server.ts (L775-L779)
Thanks to latest improvement of the edge-runtime in 1.1.0-beta.4, we can now catch unhandled rejection and uncaught exception, and decorate them.
### How to test?
Please reuse the existing tests who already covered these cases:

This PR fixes an issue where we have a middleware that rewrites every single request to the same origin while having `i18n` configured. It would be something like:
```typescript
import { NextResponse } from 'next/server'
export function middleware(req) {
return NextResponse.rewrite(req.nextUrl)
}
```
In this case we are going to be adding always the `locale` at the beginning of the destination since it is a rewrite. This causes static assets to not match and the whole application to break. I believe this is a potential footgun so in this PR we are addressing the issue by removing the locale from pathname for those cases where we check against the filesystem (e.g. public folder).
To achieve this change, this PR introduces some preparation changes and then a refactor of the logic in the server router. After this refactor we are going to be relying on properties that can be defined in the `Route` to decide wether or not we should remove the `basePath`, `locale`, etc instead of checking which _type_ of route it is that we are matching.
Overall this simplifies quite a lot the server router. The way we are testing the mentioned issue is by adding a default rewrite in the rewrite tests middleware.
In a previous PR (#19032), we added a hard error during `next export` if the default Image Optimization API is being used because it requires a server to optimized on demand. The error message offers several different solutions but it didn't consider that by the time someone runs `next export`, they are probably done writing their app.
So if `next export` is a hard requirement, the quickest path forward is to disable Image Optimization API. So this PR adds a new configuration option to `next.config.js`:
```js
module.exports = {
images: {
unoptimized: true
}
}
```
### Update
Upon further discussion, we might want to avoid doing this just for images and instead introduce a top-level config to indicate export is coming and then handle errors or warn for [unsupported features](https://nextjs.org/docs/advanced-features/static-html-export#unsupported-features).
```
module.exports = {
nextExport: true
}
```

This improves the warning thats printed when you have experimental features enable so its clear which ones are enabled (in parenthesis) and where they are enabled (in next.config.js or next.config.mjs)
## Before
```
warn - You have enabled experimental feature(s).
```
## After
```
warn - You have enabled experimental features (reactRoot, serverComponents, scrollRestoration) in next.config.js.
```
In Middlewares, dynamic code execution is not allowed. Currently, we warn if eval / new Function are invoked in dev but don't warn another dynamic code execution in WebAssembly.
This PR adds warnings for `WebAssembly.compile` and `WebAssembly.instantiate` with a buffer parameter (note that `WebAssembly.instantiate` with a **module** parameter is legit) invocations. Note that other methods that compile WASM dynamically such as `WebAssembly.compileStreaming` are not exposed to users so we don't need to cover them.

Shallow route changes did not work for rewritten pages when Middleware
was used, and made hard refreshes, although it was possible with static rewrites.
This happened because the router has a manifest of the static rewrites,
allowing static rewrites to map the route before comparing with the
local cache.
Middleware rewrites are dynamic and happening on the server, so we
can't send a manifest easily. This means that we need to propagate
the rewrites from the data requests into the components cache in
the router to make sure we have cache hits and don't miss.
This commit does exactly that and adds a test to verify that it works.
This fixes#37072 and fixes#31680
_Note:_ there's one thing that is somewhat an issue though: if the first
page the user lands on is a rewritten page, and will try to make a
shallow navigation to the same page--we will make a `fetch` request.
This is because we don't have any client cache of the `rewrite` we just
had.

In a previous PR (#34075), the ISR behavior was introduced to the Image Optimization API, however it changed the cache-control header to always set maxage=0. While this is probably the right behavior (the client shouldn't cache the image), it introduced a regression for users who have CDNs in front of a single Next.js instance (as opposed to [multiple Next.js instances](https://nextjs.org/docs/basic-features/data-fetching/incremental-static-regeneration#self-hosting-isr)).
Furthermore, the pros of client-side caching outweight the cons because its easy to change the image url (add querystring param for example) to invalidate the cache.
This PR reverts the cache-control behavior until we can come up with a better long-term solution.

* Re-introduce Edge API Endpoints
This reverts commit 210fa39961, and
re-introduces Edge API endpoints as a possible runtime selection in API
endpoints.
This is done by exporting a `config` object:
```ts
export config = { runtime: 'edge' }
```
Note: `'edge'` will probably change into `'experimental-edge'` to show
that this is experimental and the API might change in the future.
* Support `experimental-edge`, but allow `edge` too

This ensures we use the correct dynamic route params favoring params from the URL/matched-path over route-matches. This also ensures we properly cache `_next/data` requests client side when the page is not a `getServerSideProps` page.

I know the `contributing.md` doc said to avoid adding new tests to `integration`. It also said new tests should be written in TypeScript.
I wasn't sure where to put the tests for this so I went with `integration`. I also didn't see many other tests written in TS in this part of the codebase so I stuck with `.js`.

This PR moves the internal logic associated with `req.ua` into an explicit method the user should to call to have the same behavior.
**before**
```typescript
// middleware.ts
import { NextRequest, NextResponse } from 'next/server'
export function middleware(request: NextRequest) {
const url = request.nextUrl
const viewport = request.ua.device.type === 'mobile' ? 'mobile' : 'desktop'
url.searchParams.set('viewport', viewport)
return NextResponse.rewrites(url)
}
```
**after**
```typescript
// middleware.ts
import { NextRequest, NextResponse, userAgent } from 'next/server'
export function middleware(request: NextRequest) {
const url = request.nextUrl
const { device } = userAgent(request)
const viewport = device.type === 'mobile' ? 'mobile' : 'desktop'
url.searchParams.set('viewport', viewport)
return NextResponse.rewrites(url)
}
```

## Bug
fixes#37106
Please note that, as for `pages/` the `src/middleware` file is ignored when `/middleware` is present.
## How to test
1. Rebuild next.js `pnpm build`
2. Run dedicated tests: `pnpm testheadless --testPathPattern middleware-src/`
`safariNomoduleFix` was first introduced back in the year 2019 (#7704) as a part of the `modern` experimental feature. The experiment is ended and the feature is removed a year later in #19275. However, the unused `safariNomoduleFix` is never removed, until now.
* rewrite head side effects component in hooks
* remove mapping from element to children in head manager since they're already the children of `<Head>`
When move `SideEffect` to hooks, the effects scheduling is earlier than life cycle. We're leverage layout effects and effects at the same time, always cache the latest head updating function in head manager in layout effects, and flush them in the effects. This could help get rid of the promises delaying approach in head manager.

There was a bug that ignored `Request` options when one was given to the `fetch` function:
```ts
const request = new Request("https://example.vercel.sh", { method: "POST" });
await fetch(request);
```
The code above was expected to make a `POST` request, but instead it
made a `GET` request.
This commit fixes it and adds some tests to verify that fetching with a
`Request` object works as expected, and therefore resolves#37123.

This commit lets users measure their Interaction to Next Paint [INP](https://web.dev/inp/) web vital.
Note that the `web-vitals` package is beta to denote that INP is an experimental metric, the code is stable and v3 is backwards compatible.
`web-vitals` CHANGELOG for v3:
- [BREAKING] Report TTFB after a bfcache restore
- [BREAKING] Only include last LCP entry in metric entries
- Add support for the new INP metric
- Rename getXXX() functions to onXXX()
- Add a navigationType property to the Metric object
See https://github.com/GoogleChrome/web-vitals/blob/next/CHANGELOG.md
Upgraded `playwright-chromium` from `1.14.1` to `1.17.2` because the Events Timing API used to measure INP is only available in Chromium >= v98.

Duplicate locales will lead to an obscure error message at build time, here I caught them earlier.
Using a Set sounded the terser and fastest approach, but it won't tell which locale is duplicated.
Also I've noticed that the "Array.isArray" check happens twice on i18n.locales? Maybe it's on purpose?
