Remove the Server CSS manifest and related logic, and use the chunkGroup
CSS files instead for each entry to inject stylesheet links.
Why was that manifest needed in the first place? When implementing CSS
collection for RSC and nested layout initially, we collect CSS imports
at each layer and create corresponding client entries. But then soon got
hit by the problem of duplication and improper tree-shaking. Two layers
can have the same CSS imported so we solved it in a way that "if an
upper layer imports this module, skip it in child layers". Note that
this is deduped by module, so we need to keep the information of "layer
(entry) → CSS modules" somewhere, in a manifest.
Another reason is that we create the client entry before Webpack
optimizes modules, so we can inject the client entry into the same
compilation. But that means the collected client modules from the server
layer are not properly optimized (DCE). **This is a general issue at the
moment that's not specifically related to CSS, although using that
manifest to collect DCE'd info and join the original collected CSS files
with that info temporarily solved it.** That's why I disabled some tests
related to font CSS collection and want to improve it in a more general
way.
Why is that not needed anymore? Main reason is to keep a good balance
between duplication and number of chunks, and delegate the decision to
Webpack's splitChunks plugin. It is not possible to get to a point of 0
duplication unless we ship every CSS module as a single chunk. And since
in #50406 we made the duplication better but at the chunk asset level,
instead of the original module level.
Prior work: #50406, #50610.
### What?
Fixes https://github.com/vercel/next.js/issues/50129
### Why?
The current denormalization of app dir paths doesnt account for the
normalization done in `normalizeAppPath`, causing build log outputs for
certain paths such as anything under a route groups to be incorrect
### How?
There's 2 ways this could be fixed:
1.) Denormalize the app dir paths by reading the
`app-path-routes-manifest.json` and mapping back to the original file
path
2.) (what I chose to do) Normalize the keys of `appBuildManifest`
### Result
App dir paths, including route groups, now have their correct output
size

This cleans up some setup functions within the route modules, improves logic around headers, and handles the case where the URL is invalid better for routes using the request adapters.
Similar to tags and paths, when `cookies().set()` is called we have to
invalidate the client router cache as well so routes with
`cookies().get()` will not holding the stale data. This is critical for
auth and other scenarios.
In the future we can have an optimization to only invalidate routes that
actually rely on cookies, similar to paths.
This PR fixes a few reports that we were double fetching when navigating via a link that had prefetch false.
## Context
The bug was happening because we were inadvertently eagerly fetching even if we potentially bailed out of the optimistic navigation, which would then trigger another fetch from going through the regular navigation path.
There's potentially another bug here where we should potentially not bail out of optimistic navigation in the cases reported but we can fix that later.

## What?
While looking at the CPU profile of booting up Vercel's site I noticed
that we call `getPageStaticInfo` a lot. Looking into this more it turns
out `getPageStaticInfo` is currently called for all routes, `pages` and
`app`, even though the data is only being used to keep track of which
routes are edge functions, however, this is already tracked as part of
the build output so this didn't make sense to me. First I tried
commenting out this entire block and all tests were passing, so I
removed it except for middleware as middleware can provide a `matcher`
which does need to be known before compiling the file as of right now.
After that change a different set of tests started failing, specifically
the one that checks if we warn correctly. Interestingly by fixing
`getPageStaticInfo` being called early and for all routes it also caused
these warnings to no longer trigger as there was a case in the manifest
plugin that called `getPageStaticInfo` with less information. Calling
`getPageStaticInfo` there was not needed either as we call
`getPageStaticInfo` at the beginning of the build for each entrypoint so
we already have the information required, it just had to be passed down
so that the manifest plugin could use it.
For Vercel's site this change improves booting the dev server by over 1
second.

When navigating to a route with a hash parameter, the layout router
jumps to the element by scrolling to the node's `offsetTop` value.
However, this will ignore `scroll-padding`, which deviates from browser
behavior.
It looks like this isn't an issue in the pages router which currently
makes use of
[`scrollIntoView`](https://github.com/vercel/next.js/blob/canary/packages/next/src/shared/lib/router/router.ts#L2262).

Tweak code owners after some testing and feedback.
- Move the Next.js team up to be optional global code owners (so that everyone can review but are not tagged for review). Global individuals should still be tagged if there are no specific `.vercel.approvers` files in subdirectories.
- Adds @vercel/devex to image files so there's coverage on those files for the docs
- Target specific folder and files for Styfle to get notified
- Deletes some rules in the old GitHub codeowners
Both of our bundlers won't split different exports of a module into different chunks, we can rely on https://github.com/facebook/react/pull/26624 to simplify the structure. This reduces the size of the client reference manifest by ~70%.
Fixes#50232
Passing down the private env into `'render-server'` module to pick up the proper react with require-hook in standalone server
fix NEXT-1260
We already have a warning when using `next export` with `output: export` because the `next export` is effectively a no-op (the exported output was already generated during `next build`).
However, this PR ensures that `next export -o <dir>` throws an error when `output: export` is defined because the files were already emitted to the `distDir` in the `next build` step and we can't safely no-op at this point.
We also guide the user to the correct solution which is to use `output: export` along with `distDir: <dir>` in your next.config.js (instead of mixing legacy behavior with the new behavior).

Follow up for #50548
There're some packages like `aws-sdk-js-v3` which doesn't have a exports field yet:
```
"main": "./dist-cjs/index.js",
"types": "./dist-types/index.d.ts",
"module": "./dist-es/index.js",
```
This PR let u pick up by the js assets based on main fields, will prefer `"module"` field instead of `"main"`
Closes NEXT-1286
Add a `NEXT_CPU_PROF` environment variable to programmatically profile CPU for the router worker and two render workers. This is helpful because the `--cpu-prof` isn't reliably writing the result (#27406) especially with our multi-process architecture.
Adding a `_rsc` query for RSC payload requests so that they can be
differentiated on resources level for CDN cache for the ones that didn't
fully respect to VARY header.
Also stripped them for node/edge servers so that they won't show up in
the url

Closes NEXT-1268
This is a temporary fix before we can ship #51018 (more details there). If there're multiple chunk groups holding the same CSS module, we use files from the first one. This has some flaws but still better than our current status.
Like how we handled RSC loader transform before, we also apply swc
loader to middleware to make sure the imports optimization is applied so
og package won't be bundled

### What?
When `verbatimModuleSyntax: true` is set, `isolatedModules: true` are not allowed by TS
### Why?
Next always adds `isolatedModules: true` which causes TS error.

There are some incoming docs / MDX changes where prettier will throw an error when using the older version. Updating prettier before I bring in those changes.
Looks like the most notable change is adding parentheses around `typeof` checks in TypeScript.
**Before**
```
export type Locale = typeof i18n['locales'][number]
```
**After**
```
export type Locale = (typeof i18n)['locales'][number]
```
We need to spread the module into an object instead of access the module exports that could not exist, to avoid triggering the warning. Fix the bad loader change introduced in #50548
```
