### What / why?
Currently there is a bug because the `subTreeData` can only be applied
once, however, we reuse the same response when a url was prefetched.
During the first render of the response we apply the cacheNodes and then
these should be reused for subsequent navigations. There's currently a
bug because `fillLazyItemsTillLeafWithHead` creates `LAZY_INITIALIZED`
cache nodes that don't copy the previous cache node `parallelRoutes` and
`subTreeData` value, causing the cache nodes below where the
`subTreeData` is applied to be deleted from the cache, even when they're
not affected by the navigation.
### How?
This PR adds copying of the cache node when it exists already, I've
added a marker for `wasPrefetched` to trigger that behavior but in
talking to @feedthejim about this it seems we can swap to this behavior
always when applying the server response, that needs to be discussed
further though, this is temporary implementation with the fix for routes
that were prefetched.
Fixes NEXT-402

Since both `exportPage` and `isPageStatic` methods in the static
optimization worker involve loading the actual page component, it's
better to assign the same page to the same worker for these 2 tasks to
avoid unnecessary memory allocation.

This ensures we properly honor the `export const fetchCache` config and
also ensures we properly bypass fetch-cache when an On-Demand
Revalidation is occurring.
The `export const dynamic` handling is not changed here as that was
behaving correctly and should not influence fetch cache handling only
whether a page is prerendered fully or treated as SSR.

Fix the module resolving error found during development, because now few
app route code is bundled into RSC server layer, it can't resolve
opentelementry properly and will throw the error blow due to the check
of `require('@opentelemetry/api')` to see if it's installed.
```
Module not found: Can't resolve '@opentelemetry/api'
```
Thus I alias it to default `next/dist/compiled/@opentelemetry/api` when
it doesn't have external module
---------
* use `check` to wait for css change
* remove unused swr deps and update them to latest
* remove swr esm test in `app-dir/app/` since it's already covered in
`app-dir/app-external/`

For backward compatibility, we only handle `favicon.ico` file to
generate `/favicon.ico` route and link tag. If you want to use other
extension such as `png`, use `icon(\d)?.[ext]`
Fixes#46993.
The issue is introduced in #46705 by @ijjk
Next.js uses `jest-worker` for multiprocessing. `jest-worker` supports both `child_process` and `worker_threads` modes. Next.js use `child_process` mode by default, but can also switch to using `worker_threads` mode with an experimental flag `config.experimental.workerThreads`.
In #46705, @ijjk applies a fix that works for the `child_process` mode, which breaks the `worker_threads` mode (`jest-worker`'s `NodeThreadWorker` interface doesn't have the private property `_child`), causing static HTML export to fail with the following error (#46993):
```
> Build error occurred
TypeError: Cannot read properties of undefined (reading 'on')
at createWorker (/Users/[redacted]/node_modules/next/dist/lib/worker.js:32:31)
at new Worker (/Users/[redacted]/node_modules/next/dist/lib/worker.js:42:9)

at async Object.build [as default] (/Users/[redacted]/node_modules/next/dist/build/index.js:74:29)
```
The PR fixes that.
### What?
see also https://github.com/vercel/turbo/pull/4415
We need a full process polyfill to fix some edge cases
Also disables SourceMap for edge chunks, since they are not used
### Why?
Some packages do weird things, e. g.
```
var isBrowser = process.title === 'browser'
```

- closes WEB-766.
This PR enables a new job for running tests, against turbopack. Since we
have observed some flakiness across turbopack test execution, it starts
from absolute minimum set of tests to not block any CI due to unexpected
failure.
Ran manual workflow roughly ~50 times and looks like these set of tests
are fine to make it as blocking check for the PR. In the future, depends
on the stability we'll increase number of test gradually.
This ensures we don't normalize locales in the URL with the
skipMiddlewareUrlNormalize flag enabled so that casing redirects can be
applied correctly for locales.
Turbopack starts up the router process with all ENV values, but the edge
function definition didn't list any `env` keys for the function
invocation. So, middleware couldn't access any ENV values.
Turbopack doesn't currently have a way to determine what ENV keys are
actually used by the source program, so I'm just passing everything
defined. I'm not sure if that's an issue during dev (I could see it
being one for the build process, but that doesn't matter for this case).
Fixes#47766
Fixes WEB-831
Fixes WEB-834
This ensures we check if a path is `appRouter` during prefetching so
that we can trigger hard navigations quicker when routing from pages ->
app. An additional config is also exposed to allow configuring the
potential false positive rate for the client filter.

Paired with https://github.com/vercel/turbo/pull/4329, this implements
streaming responses for App and API renders. This is accomplished by
sending an initial `headers` message (carrying the status code and
headers list), N `body-chunk` messages of bytes, and a final `body-end`
message to signal completion.
Once sent to Turbopack, these chunk messages will be streamed out of the
node rendering process directly into the HTTP server's response.
Closes WEB-27

Fixes an issue with newer app directory usage:

Type error: ',' expected.

---------
Allow to use relative paths which starting with dot (e.g. `./[paths]`) for urls under `metadata.alternates`.
This allow user to simplify setting `canonical` or other such like `languages` once in root layout with `metadataBase` and a simple relative path, then next.js will resolve it with current pathname of the page.
For example
```js
export const metadata = {
metadataBase: new URL('https://mydomain.com'),
alternates: {
canonical: './'
}
}
```
Then:
for page `/` it will generate `https://mydomain.com`;
for page `/about` it will generate `https://mydomain.com/about`
as your cononical url
Closes NEXT-897
### Minor changes
- always remove trailing slash for `URL.href`
## What
This fix serves to address issues where multiple `Set-Cookie` headers
were combined in some runtimes.
## Why
This is because `set-cookie` behaves differently than other headers in
some cases.
Eg. when iterating on a `Headers` instance, multiple set-cookie headers
are folded. To set them correctly, we need to split them. But it'd not
be enough to naively split on the first occurrence, because `,` is a
valid cookie value when for example it's used in `Expires` in a date
string.
So we use a method to correctly detect where to split the cookie.
This should fix all runtimes.
Note, the spec now has `Headers#getSetCookie` which should be preferred
if it's present. https://github.com/whatwg/fetch/pull/1346. We are using
the [`edge-runtime`](https://github.com/vercel/edge-runtime), so this
should be fixed upstream and then reused in Next.js in the future.
## How
Wherever we can, we reuse the `fromNodeHeaders` and `toNodeHeaders`
methods that have the correct implementation. This should be preferred
in the future in other parts of the codebase. We fixed some related TS
issues as well.

### What?
This PR adds an internal compile time flags for the `next-swc`, which exposes two runtime apis into next.js to initialize heap-profiling enabled memory allocator and teardown those once next.js exits. While there are newly added 2 js interfaces (`initHeapProfiler`, `teardownHeapProfiler`) underlying napi binary itself have compile time flags to actually enable those feature: any user who runs npm-published next.js cannot enable this features with any kind of runtime configuration. Only manually built next-swc binary with specific flag can enable this. Since this is primarily for the CI testing workflow only, those flag / configs are not visibily exposed as well.
### Why?
It is for some experiments on the CI to see if it can observe some of memory pressure issues (WEB-593, WEB-804) while it is not easily reproducible on the local machines.
This PR adds a test to confirm that the component will be committed
after the stylesheet is loaded, by delaying the CSS request in
middleware and then check the active style in `useEffect` (technically
it should be `useLayoutEffect`). Since our current timeout for that is
set to 500ms, I also added a test with 1000ms delay to rule out false
negative cases.
Based on some suggestions from @sokra, this serves to unify the Route Handlers and Route Modules to provide a unified interface for defining route modules and handlers and defining their dependancies.
