### What
This pr addresses an issue in Docker where the cache and the creation of
its contents throw the following error:
```
[Error: EACCES: permission denied, mkdir '/app/.next/cache'] {
errno: -13,
code: 'EACCES',
syscall: 'mkdir',
path: '/app/.next/cache'
```

### What?
This PR removes an unnecessary await keyword from the
writeSema.release() call. The release method does not return a promise,
hence awaiting it is not required.
### Why?
Awaiting on writeSema.release() which does not return a promise can lead
to confusion and potentially hinder performance. By removing the await
keyword, the code is simplified and aligns with the intended synchronous
nature of the release method.
### How?
Reviewed the writeSema.release() method implementation to confirm it
does not return a promise.
Removed the await keyword from the writeSema.release() call to ensure
the code correctly reflects the synchronous operation.

### What?
This fixes a special case where rewrites wouldn't work when resuming a
dynamic page.
### Why?
Previously, as routes would direct-match against entries in the cache,
this takes the `x-matched-path` as the source of truth for these
requests if the `x-now-route-matches` header is not present.
## What?
Working on some refactors to fix a bug with `undefined` handling for
Turbopack. This is the first step by making define-env-plugin.ts have
stricter types so that we can easily find which values are set to
`undefined`.

The value `undefined` can be saved to the incremental cache as
`undefined` (`JSON.stringify(undefined)`) with no errors, but when
retrieving it, we attempt to parse it as JSON using
`JSON.parse(undefined)`. This throws an error. We should instead
deserialize `undefined` as `undefined` when retrieving.

### What?
Make a note about the new `$ACTION_` properties in the `formData`
### Why?
Since `next@14.1.3`, some new `$ACTION_` properties have appeared in
the`formData`, which cause validation errors when used with a strict
validation with a library such as Zod or Yup:
```tsx
// Form Client Component
export default function Form() {
const [state, formAction] = useFormState(action, {
type: 'initial',
});
return (
<form action={action}>
{/* ... */}
</form>
);
}
// Server Action
export async function action(
prevState: ServerActionReturnValue,
formData: FormData,
): Promise<ServerActionReturnValue> {
const validationResult = await schema.validate(
Object.fromEntries(formData.entries()),
);
```
The errors from Yup:
```
Errors:
- this field has unspecified keys: $ACTION_REF_1, $ACTION_1:0, $ACTION_1:1, $ACTION_KEY
```
The data in the `formData.entries()`
```js
{
'$ACTION_REF_1': '',
'$ACTION_1:0': '{"id":"59f475b...","bound":"$@1"}',
'$ACTION_1:1': '[{"type":"initial"}]',
'$ACTION_KEY': 'k187677481',
// Real form data starts here:
year: '2024',
```
### How?
Document additional properties with keys starting with the prefix
`$ACTION_`
### Alternatives Considered
Maybe these `$ACTION_` properties are not intended to be exposed to
users, and should be stripped before the `formData` reaches the Server
Action.

### What?
Bringing Turbopack for Next.js documentation from `turbo.build` to
`nextjs.org/docs`.
> Note: After this PR lands, there will be a subsequent PR to
`vercel/turbo` to remove these docs from `turbo.build` and redirect
here.
### Why?
Previously, this documentation was on `turbo.build`. This was confusing
because these docs weren't specific to Next.js. Rather, they are for
Next.js developers who want to configure their bundler (which happens to
be Turbopack under the hood).
We had seen a number of times that folks were unable to find loader and
configuration support for the their Next.js + Turbopack applications so
this PR should help surface that information better where folks are
looking for it.

### What
context: https://vercel.slack.com/archives/C04KC8A53T7/p1709908007968319
Current test flakyness keeps changing the latest data from
areweturboyet, so instead of relying on each run's data trying to use
manifest's known good instead.
Closes PACK-2698
### What
Exclude the cases like external urls and relative urls with query from
appending trailing slash when it's needed.
The process is:
- If it's a uncertain string path (relative url, could start with `'./'`
or `/`), convert to relative that starts with `/`;
- then we covert the url (string or URL) to string url
- We do the check if we need to append the trailing slash
### Why
In #62109 we added functionality that can only append trailing slash
when we appended trailing slash to some metadata url like `canonical`
url and open graph url when the config is enabled.
For urls with queries, the trailing slash can also be omitted.
For the external urls (different origin comparing to `metadataBase`) we
don't need to append trailing slash as they're not the same web app.

### What?
Switch Yarn v1 to pnpm for reproduction repos, avoiding the CodeSandbox
Yarn v1 `yarn.lock` caching problem described below
### Why?
As confirmed with @CompuIves, CodeSandbox caches the `yarn.lock` file
generated after the first start + `yarn install` of a GitHub template
(Yarn v1) - this saves old versions of Next.js (not the latest canary)
in the lockfile and causes old versions of Next.js to be installed when
users click on the CodeSandbox Reproduction link during issue creation.
This leads to the current breakage, where Next.js actually cannot even
start in the reproduction sandbox:
1. Start creating a new GitHub issue on the `vercel/next` GitHub repo
2. Open [the CodeSandbox reproduction
link](https://codesandbox.io/p/sandbox/github/vercel/next.js/tree/canary/examples/reproduction-template)
linked in the **Link to the code that reproduces this issue** section
3. Observe the error message below in the `dev` task started below
(`experimental.appDir: true` was required in the `13.0.8-canary.0`
version of Next.js in the cached `yarn.lock` file, but the
`next.config.js` file no longer includes this config)
```bash
$ yarn dev
yarn run v1.22.19
$ next dev
ready - started server on 0.0.0.0:3000, url: http://localhost:3000
Error: > The `app` directory is experimental. To enable, add `appDir: true` to your `next.config.js` configuration under `experimental`. See https://nextjs.org/docs/messages/experimental-app-dir-config

This uses CodeSandbox-specific config

An iteration of #62359, this uses the module-local flag instead of a
shared dedicated module for flagging runtime errors, correctly reloading

Test Plan: See now-passing tests in the manifest.
Closes PACK-2690
The "Compiled" HMR log is emitted as follows:
> Compiled in 54ms
When running this string through the matcher, we get:
```
> const matches = "Compiled in 54ms".match(/Compiled.*? in ([\d.]{1,})\s?(?:s|ms)/i)
console.log(matches[1]); // 54
```
We correctly assign `compileTime` to `matches[1]`. However, we then
assign `compileTimeMs` to `parseFloat(compileTime[1])`. This is
definitely an error, as `compileTime[1]` would be `4` in the above
example.
This means that if the compilation time takes less than a single digit
value, it'd be coerced to NaN.

### What
Use the plugin state directly in flight plugins to access the async
modules collection
### Why
This change is cherry-picked from #62349 , where I found the plugin
state didn't store the async modules reousces properly due to the clone
of the array in flight manifest plugin. So for flight manifestp plugin
itself, it's holding a different instance rather than the one from proxy
state.
Closes NEXT-2743
#62980 migrated `examples/basic-css` to use app router. A handful of our
create-next-app tests use this example when asserting the correct
project files are created, so we were asserting on a pages file existing
rather than an app dir page. This PR updates those tests.

are loaded.

### What
Looks like we allow d.ts to be included in `match_js_extension`, so if
custom rules have an ecmatransform it could raise an error with d.ts.
This doesn't make test passes yet, seems there are other issues need to
be resolved.
