This ensures we don't pass through the signal field when revalidating a
fetch as that can be delayed and we don't want to abort the
revalidation.

### What?
* add support for middleware manifest and edge adapter for pages API
routes
* improve the error reporting a tiny bit
### Why?
### How?
Closes WEB-1428
When `fallback: false` is set and you visit a dynamic segment (e.g. `/[slug]`), the router server was getting stuck in a `x-no-fallback` loop and eventually would fail because it was matching the output at `check_fs` before attempting to resolve dynamic routes in the `check: true` block.
Closes NEXT-1557
This PR adds missing parameters to the `useSelectedLayoutSegment` & `useSelectedLayoutSegments` hooks since they take *optional* `parallelRoutesKey`.

This is the first step to enable the automatic "modularize imports"
optimization for some libraries. It transforms named imports like
`import { A, B, C as F } from 'foo'` to a special loader string: `import
{ A, B, C as F } from "barrel-optimize-loader?names=A,B,C!foo"`.
In a follow-up PR we'll apply corresponding optimization with another
SWC transformer.
### What
When the global `window.Promise` is proxied, things that rely on custom Promise properties (e.g. the `status` field) break. In the case of navigation events, the prefetch cache is never identified as being fulfilled, so navigation hangs in an infinite loop.
### How?
This ensures that the value being stored in the prefetch cache have the expected Promise signature even when proxied.

We initially wrote the [React
page](https://nextjs.org/docs/getting-started/react-essentials) to
introduce Server Components in the App Router, but over time, some
implementation details have changed, and the information has become
stale. The React team is working on adding new docs, so I'd like to
change the narrative on the Next.js docs from "client vs. server
components" to "writing code for the server and for the client" - and
link back to the React documentation when it becomes available.
As React developers, we're very familiar with writing code for the
client, it's nice and simple. But doing so comes at the expense of not
being familiar with the server. The aim of these docs is to help
developers become proficient in both the client and server environments.
I'd like to take it back to the foundations, and not use abstractions
like SSG and CSR, MPAs or SPAs, as those terms come with their own set
of assumptions that make it harder to understand how RSC works. Instead,
we'll focus on the request lifecycle, show how application code flows
from the server to the client, and discuss the trade-offs of doing
operations in each environment.

This fixes a `CurCacheHandler is not a constructor` error when the custom cache handler path is transpiled from ESM -> CJS (resulting in the handler being attached to the `default` property on the module's exports)
Closes NEXT-1558
Fixes#54453
### Why?
Many developers are asking how to add internationalized routing in the App Router as it works in the Pages Router. [next-i18n-router](https://www.npmjs.com/package/next-i18n-router) is a very helpful package that fully solves this challenge.
### How?
Unlike the example provided in these Next.js i18n docs, [next-i18n-router](https://www.npmjs.com/package/next-i18n-router) does not require nesting all pages in a `[lang]` dynamic segment. It also allows for the default language to be accessible without a locale prefix in the path (just like in the Pages Router).
It includes locale detection based on the `accept-language` header as recommended in the Next.js docs, as well as support for the `NEXT_LOCALE` cookie to set a user's preferred language (just like in the Pages Router).
This:
- Includes Next.js version as metadata
- Includes `navigation-to-hydration` timings (note: this metric still needs to be refined to better capture complete hydration)
- Updates `client-hmr-latency`'s `updatedModules` to be of the form `[project]/foo.js` instead of `./foo.js`, aligning with other events.
Closes WEB-1429
This removes the client-side polling logic that we're doing on every HMR
tick in favor of events like `addedPage` / `removedPage`. It was leading
to a lot of misc issues & confusion surrounding error/404 pages being
polled needlessly.
Instead this updates `addedPage` / `removedPage` to be emitted on the
server, so that we can leverage those hooks to reload when necessary.

Closes NEXT-1372

Seems this sometimes pulls from pnpm cache instead of checking for newer canary version so this updates to use `pnpm add` instead which should help here.
This decreases the aggregate event timeout for WatchPack in development to `5ms` which should improve the performance of reloading routes for users developing Next.js applications.
## What
Adds a reworked version of webpack's [built-in memory cache garbage
collection
plugin](853bfda35a/lib/cache/MemoryWithGcCachePlugin.js (L15))
that is more aggressive in cleaning up unused modules than the default.
The default marks 1/5th of the modules as "up for potentially being
garbage collected". The new plugin always checks all modules. In my
testing this does not cause much overhead compared to the current
approach which leverages writing to two separate maps. The change also
makes the memory cache eviction more predictable: when an item has not
been accessed for 5 compilations it is evicted from the memory cache, it
could still be in the disk cache.
In order to test this change I had to spin up the benchmarks but these
were a bit outdated so I've cleaned up the benchmark applications.

### Problem
One style of `not-found` has `precendence` property with "undefined" value, which can't be handled by React Float, then during navigation the style could not load properly, lead to the style missing in issue #53210.
### Solution
Always enable `precendence` for all links, so all the css styles of page and convention components can be hoist by react properly. Float will decide which one should be handled. Previously this change only applies to template, actually we can apply it to all components so that they can all be handled properly especially during client navigation.

Follow up for #54202, use swc AST to determine the directives. Also add server actions directives for extendibility here in case we might need it in the future
Closes NEXT-1538
For the server compilation, we currently transpile the dynamic import
expression to `null` if `ssr` is disabled. However to make the Server
Actions layer work (as it can be created again from a Client Component),
we can't do that optimization.
This PR changes it to always keep that import expression when
`react_server_components` (App Router) is enabled, no matter which layer
it's on.
Closes#52672.
When `"use client"` directive appears after other statements, it should
be ignored instead of treat as client components. There's a bug inside
swc transform that we should mark the directives detection is "finished"
after other non string literals directives AST nodes are detected before
the first directive

### What?
Let Next.js enable React Strict Mode by default for the App Router.
This caught a bug with the `AppRouterAnnouncer` added in #47018 which
should be fixed as well.
### Why?
This logic:
a0d1d728b9/packages/next/src/build/webpack-config.ts (L326-L333)
assumes that the default value of `reactStrictMode` is `null`, but it
was set to `false` in #46656.
### How?
This PR reverts the default value to `null`.

Fixes#53315

Previously we were appending the data routes to the dynamic routes array
which didn't ensure the data routes come before the normal dynamic
routes allowing a catch-all to override the data route.

This PR merges the app renderer worker into the router process. This
improves the memory overhead mostly.
There're future work to do to get rid of the IPC server for router and
app renderer, as they're now merged in one process.

- Updates wording on nesting, to say it's not the actual output, but rather how `template.js` nests between `layout.js` and its children.
- Remove mention of animations, needs further clarification.
