### What?
* fix app dir chunking
* fix app dir 404s
* improve app dir performance
* rerender shadowportal on errors to re-add nextjs-portal to avoid empty
page
* inject polyfills before user code
* fix manifest generation
see also https://github.com/vercel/turbo/pull/4488
### Why?
App dir was very slow and lead to 404 errors
### How?
add included metadata to chunks to allow deduplicate chunk loads at
runtime
### 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
This is the Next.js side of https://github.com/vercel/turbo/pull/4397

### What?
Refactors the resolving logic for the `app` loader tree. This PR ensures
it's used to create entrypoints in turbopack. Next up is integrating it
into the webpack build too.
These changes also ensure that parallel routes resolving is applied,
which previously wasn't supported in turbopack.
### Why?
Part of the effort to deduplicate critical logic between
turbopack/webpack in Next.js, this will help land features in
turbopack/webpack at the same time.
### How?
Quite a few changes. @sokra helped a ton on this PR. `app_structure.rs`
was changed to the new resolving logic so most of the logic is there.
Additionally we added support for calling the same function in two ways
from Node.js: `turbo.entrypoints.get` and `turbo.entrypoints.getStream`.
`get` can be used by `next build` to get the full list of
entrypoints/loadertrees once. `getStream` has watching built-in and
calls a callback function with the new list anytime a file is added that
would change the loadertree.

### 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'
```
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

### 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.

### What?
Part of WEB-736.
This PR refactors imports to turbopack to turbo-binding, as same as we
used to do with next-binding. Current next-binding in this repo doesn't
make sense anymore and removed. There are no functional changes. This'll
reducwe surface for the imports and also will make easier to run
integration test over latest turbopack.
Note swc dependency is not reflected in this PR yet - following PR will
update those imports.
Fixes WEB-787.
This implements automatic font fallbacks for `next/font/local`. It uses the `allsorts` library to query font metrics across woff and ttf fonts.
Test Plan: Now passes 24 Next.js integration tests, up from 14.
Previously `next-swc` had relay transform inline, but it makes
maintenance harder. So this PR patches next-swc to use relay plugin from
`swc-project/plugins` repository.
Closes WEB-782
Fixes#47239
fix NEXT-883 ([link](https://linear.app/vercel/issue/NEXT-883))
Fun! This depends on https://github.com/vercel/turbo/pull/4251 to
implement streamed Node evaluations, giving us the ability to support
streamed middleware responses.
This is just the first step to supporting RSC streaming in Turbopack. I
chose to start with this because it requires all the same base logic,
and I understand the full router->middleware->HTTP server code path, so
it's a lot easier to work on.
Fixes WEB-738
The old `test_generator::test_resources` could only find resources relative to the project root, and not relative to the test file. Because of the new nextpack directory structure, this causes all kinds of headaches between running in nextpack and running in turbo (`next.js/packages/next-swc` vs `nextpack/next.js/packages/next-swc`).
fix NEXT-827 ([link](https://linear.app/vercel/issue/NEXT-827))
This aligns use of the next/font transform across the workspace under a
single crate, now called `next-transform-font`.
Builds on https://github.com/vercel/turbo/pull/4202 to implement custom Next.js Transformers in Turbopack.
This is the final piece to moving the `next-*` crates to Next. While we've _technically_ moved everything, Turbopack didn't support running custom transformers. So we're actually stuck on the last version we cut before deleting the next crates, running the transformers that exist in the turbopack repo. With the new support, we're almost back to the tip of main branch (there's still some snafu with `swc_core` upgrading that I'm working on).
