## What?
Currently `next build` with Turbopack fails to run in certain tests (as
expected), the problem with that is that the `afterAll()` calls assume
the server was started, which doesn't happen when the build fails, and
then causes a timeout that can't be reported if an error happens. This
change ensures the error around `server['__app']` doesn't happen.

### What?

Closes NEXT-2933
### What?
The transform seem to be quite inefficient regarding memory usage. Just
leaving a trace here to allow inspecting performance and memory of it
separately from the normal `parse` function.
Closes PACK-2855
### What
Supports root segment config inherit from layout. Currently route
segment config only runs agasint own source, so individual route segment
config works but if the config is set in layout level it is being
ignored. PR introduces root segment and pass into each route if tree
level have a corresponding layout.
Closes PACK-2839
### What
In static generation phase of app page, if there's any case that we're
receiving 3xx/4xx status code from the response, we 're setting it into
the static generation meta now to make sure they're still returning the
same status after build.
### Why
During static generation if there's any 3xx/4xx status code that is set
in the response, we should respect to it, such as the ones caused by
using `notFound()` to mark as 404 response or `redirect` to mark as
`307` response.
Closes NEXT-2895
Fixes#51021Fixes#62228
Recently the serverActionReducer was updated to no longer use React's
thenable type to carry resolution/rejection information. However the
rejection reason was not updated so now when a server action fails we
were rejecting with `undefined` rather than the rejected reason. This
change updates the reject to use the rejection value.
Closes NEXT-2943
While looking into bugfixes related to router refreshing (the other PRs
in this stack), I noticed there were situations where the `Next-URL`
header would include `/children`, or where `page$` would be present in
LoaderTree for a segment.
This updates a few spots to prevent these markers from leaking into
places they shouldn't, and shouldn't have any behavioral changes.

Previously, Next.js would buffer the `mkcert` binary in memory and write
it to disk all at once. The pull request changes this to pipe the
download stream to the disk. This improves memory consumption by
avoiding having to load the entire `mkcert` binary into memory.

This ensures that even if a `loading.js` returns `null`, that we still
render a `Suspense` boundary, as it's perfectly valid to have an empty
fallback.
This was accidentally lost in #62346 -- this brings back the
`hasLoading` prop which will check the loading module itself (rather
than the `ReactNode`) for truthiness, and I've added a test to avoid
another regression.

This PR renames the API to be not specifically related to Server
Actions, as in the future it might be used by other things. It also adds
the `__next_encryption_key_generation_promise` variable to avoid
double-generating of the key when it's called concurrently (e.g. by the
node server and edge server compilers).

### What?
### Why?
### How?
Closes NEXT-
Fixes #

### What?
This adds dynamic usage logging when the `__nextppronly` query parameter
is set and partial prerendering has been enabled. This will print the
stack trace for the accesses for all Dynamic API's that were called.
This includes those API's that were called during the flight render if
they were called before the static shell was ready.
### Why?
To take the most advantage of partial prerendering, it's important to
track where Dynamic API's are called so developers can determine what
has caused part of the component tree not to be included in the static
shell. This also helps debug situations where the error thrown by
Dynamic API's (used internally for tracking and interruption) are caught
but not re-thrown, but due to the implementation of the flight renderer
provided by React, we are unable to distinguish between errors that are
swallowed by user code or by the flight renderer.
### How?
Instead of using a boolean to track **if** a dynamic API was used, this
actually captures the stack at the callsite, allowing developers to find
the location in the codebase that invoked it.

Reverts vercel/next.js#63646
The example changes are missing a bunch of stuff:
- Types are not added, you can see the changes required here:
https://github.com/vercel/next.js/pull/63703
- Dependencies are missing, i.e. `@types/react` `@types/node`,
`typescript` are all missing.
Reverting as CI is broken.
This ensures `optimizePackageImports` doesn't unexpectedly fail to apply
for `pages` as they aren't transpiled/bundled by default without either
`transpilePackages` being used or `experimental.bundlePagesExternals`.
This also ensures our docs correctly show this config in the pages docs
as currently in only shows in `app`.

Closes NEXT-2884
## What?
Follow-up to #63665.
Ensures development tests are skipped during the production build run
for Turbopack (i.e. used to create the turbopack-build-tests-manifest).
Adds `pnpm test-dev-turbo` and `pnpm test-start-turbo` (and their
`testonly` equivalent) for running tests.
