This PR updates create-next-app's tailwind config to consider .mdx files
when it generates styles.
If you're using MDX, most of a project's styles are generated by the
other file flags, which can make it tricky to debug/notice the rare
subset from .mdx only.

### What?
Fixes a bug where `fetch()` to a page that calls `redirect()` would hang
infinitely.
### How?
The `Location` header was missing. The reason this wasn't surfaced
before is that we also inject the `<meta>` tag to redirect which the
browser would pick up to redirect too.
Fixes NEXT-997

This updates the app route handler signature to be more correct to
prevent the issue with type casting:
```diff
- (request: Request, ctx) => Response
+ (request: NextRequest, ctx) => Promise<Response> | Response
```
This also ensures that the context paramter has the correct types:
```diff
type AppRouteHandlerFnContext = {
- params?: { [param: string]: any }
+ params?: Record<string, string | string[]>
}
```
Since exiting in `setTimeout()` can cause a race condition with sending
the result from the worker and we don't want to destroy workers when
trying to leverage them as it has a perf impact this ensures we create
unique workers per usage and destroy them afterwards.

### Description
The next.js router will proxy requests if there's a rewrite with an
external URL, for POST requests this currently leads to an `ECONNRESET`,
because the client request has no body.

This PR fixes issues where rendering a new parallel route would reset
the scroll state of the page. This would be very apparent if you
scrolled down the page and opened a modal in a parallel route.
After a bit of investigating, I found out that the scroll behaviour
worked like this:
- after a navigation, we say to the router that we should auto-scroll if
possible
- but we don't specify which node of the tree should scroll
- so what happened is that the first router node to run the auto-scroll
effect would steal the auto-scroll, even though it might have been
destined for another node
The fix consists of
- when we received the flight patch, we compute all new segment paths
that will be rendered and add them to the scroll ref
- when the router says that we should autoscroll, the autoscroll
components will now read those paths and compare them with their segment
path and if yes, they will autoscroll

### What?
* move some shared runtime logic to turbopack
* use relative imports from internal code when possible
* move react-refresh logic to turbopack
* move benchmark code logic to turobpack
see https://github.com/vercel/turbo/pull/4553
### Why?
We want to have benchmarking again for turbopack PRs
We want to have a standalone turbopack cli (eventually)
We want to avoid duplicating the runtime code
### How?
refactoring, moving code
When our `run-tests` util is used we can safely only create one instance
of the package tarballs and re-use for the tests and then cleaning up at
the end.

This PR introduces a new utility function that checks the resource path,
module type, and loaders to replace the existing CSS regex in the Flight
loaders and plugins. The new function is more robust and can be extended
to correctly support other libraries such as `vanilla-extract`.

When collecting static icons we need both collect the one from layout
and page, but for root level route `/` we missed the `favicon.ico`
before so when other icon existed, the root page's collected icons will
cover root layout collected ones, which resulted into favicon missing

Closes NEXT-976
### What
Support `opengraph-image.alt.txt` and `twitter-image.alt.txt` for static
og/tw metadata image when they need to specify alt txt.
Closes NEXT-990
### Why
for og/tw images, you could have multiple images, so it's tricky to set
alt in metadata exports with alt text. For static case we want it can
work with static files, `.alt.txt` files will be the type to provide alt
text content
### What?
The change in #47985 breaks the URLs of static image files like
`/(group)/opengraph-image.png` to `/opengraph-image.png-012345`.
References from `/` are also broken.
### Why?
This is because only `opengraph-image.ts` and `opengraph-image.tsx` are
considered.
### How?
In this Pull Request, we are trying to solve the problem by including
similar support for `opengraph-image.png` and `opengraph-image.jpeg`.

In a previous PR (https://github.com/vercel/next.js/pull/46753), the
`originalSource` was saved to be passed along through the build process.
This was done a bit too late in the flow, which made `originalSource`
include some transformations.
Because `originalSource` is used for display purposes, we need it
unmodified. This PR preserves `originalSource`.
This PR fixes an issue where throwing a notFound error in a parallel
route at the top level at the root level would trigger a notfound
boundary at the parallel route level, which meant in practice that you
could still see the other slots being rendered below.
This behaviour is undesirable and was caused by the fact that we were
inserting a default one at each top-level parallel route. This is not
longer needed as we have a global one in `app-router.tsx`

This PR adds a new marker for intercepting siblings routes + adds some
validation to intercepting routes ( you shouldn't use (..) at the top
level!)
also fixes a bug with any interception from `/` when navigating from a
child route
the new marker, `(.)`, makes it easier to model cases like
```
/profile/[id]
/profile/[id]/photos/[id]/
```
With the current syntax available, you’d need to do:
```with (..):
/profile/[id]/(..)[id]/photos/[id]
with (...):
/profile/[id]/(...)profile/[id]/photos/[id]
with (..)(..):
/profile/[id]/(..)(..)profile/[id]/photos/[id]
```
now, with (.)
```
/profile/[id]/(.)photos/[id]
```

This PR basically adds support for processing multiple router payloads.
Previously we were only handling one payload at a time but now that we
introduced parallel routes, we need to be able to render and return
separate parts of the layout separately.
Before, the single payload was generated in a DFS manner: we traversed
the router state and rendered the first segment of the tree that we
found needed rendering. In practice, this meant that we could miss
adjacent segments that might need to be re-rendered as well.
Now, we iterate all branches of the tree and return an array of flight
patches to be applied on the client correctly.

Without `top: 0` the route announcer triggers subtle layout shift in
Blink/Chrome.
BTW, this mostly (possibly only?) occurs on pages with specific overflow
proprty combinations on `<html/>` and `<body/>`, and only when rendering
inside a custom element like the `<next-route-announcer />` portal.
(Changing the portal into `<div/>` seems to make the layout shift
disappear, but that would be far more invasive change than just adding
`top:0`.)

It's currently not clear that `@vercel/otel` is just a simple wrapper
when you are trying things out. So I added an excellent example of how
to instrument create an OpenTelemetry setup.
The only FUD I have here is that people won't skip that `Manual
OpenTelemetry setup` and try to understand it. But I try to describe
this at the beginning of that section.
I'll also try to update `@vercel/otel` readme to be more transparent on
what it does.
For now, this isn't a strong requirement as normal `fetch` requests will
still work with `react@next`. But in the future, form related props e.g.
`action=` and `formAction=` requires the experimental build.
Fixes NEXT-954.
Reverts vercel/next.js#48038
fix NEXT-926
---
The root cause was that when copying the package.json, I removed all
fields except for a few (such as `exports`) but missed the `browser`
field. That caused the client bundle to resolve to the Node.js version
of React DOM, and then we had the `async_hooks` error. Added it back in
99c9b9e51f8b0d4e4503ece9d07bce09161f3341.
I reproduced the error with next-site earlier and confirmed that this
fix is good.
