- [x] Make sure the linting passes by running `pnpm lint`

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.

Serverless target is deprecated, so we don't support it in Middleware as it's a new feature,
but we need to have a good error message for that. This commit solves that.

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`.

Converted AMP example over to TypeScript to match the Contribution guidelines, updated all dependencies, and made some necessary changes to allow AMP apps to build in TypeScript.
I added an additional .d.ts file, and referenced it in the tsconfig.json include array, as per the [Next.js docs](https://nextjs.org/docs/basic-features/typescript#existing-projects). These additional types are required to allow lowercase AMP elements to be a property on JSX.IntrinsicElements.
Fixes:
> Property 'amp-img' does not exist on type 'JSX.IntrinsicElements'.ts
I also replaced all occurrences of styled JSX with [@ijjk's workaround](https://github.com/vercel/next.js/issues/7584#issuecomment-503376412) to get styles in the head at build time for AMP-only pages, hybrid AMP pages, and normal pages (non-AMP).
I tried using the useAmp hook first with multiple `<style jsx>` like this [Next.js discussion](https://github.com/vercel/next.js/discussions/16755), however AMP expects a [single `<style amp-custom>` tag in the head](https://amp.dev/documentation/guides-and-tutorials/learn/spec/amphtml/#stylesheets).
Fixes:
> The parent tag of tag 'style amp-custom' is 'body', but it can only be 'head'

<!--
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:

Title self-explanatory: the package.json inside of the with-chakra-ui example template has been updated to newer versions

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.
