### What?
Bump up turbopack to latest. This is to cut off turbopack **before**
including filewatcher changes, so we can easily bisect & revert if
watcher have regressions.

### What?
This PR introduces a ground work to generate wasm bindings package from
our napi bindings. This doesn't actually replace anything yet, however
aim to establish our napi bindings package can be built against wasm32
target.
### Why?
We currently have two bindings package to generate native / wasm target
support, one for napi and one other for wasm. Recently napi-rs started
to support to generate bindings for the wasm directly - which means we
can get rid of the wasm-pack based bindings code entirely and maintain a
single bindings code only.
This'll makes our `next-swc` simpler as well, since the invocation to
the bindings now becomes identical we don't have to additional wasm
specific logics to invoke functions (i.e transform, transformsync..).
Also napi generates wasi-supported wasm bindings, provides few more
features to the current wasm bindings.
#### Good
- Async napi binding fn works transparently (`transform`, `minify`...)
- (Experimental) thread supports depends on node.js runtime
- Wasi support: i.e it can even read filesystem directly!
#### Things to consider
- node.js's wasi support is experimental yet
- napi-rs's wasm support is in beta yet, specifically `packaging`
generated wasm output.
Due to `things to consider` reasons, this PR does not replace existing
wasm target yet. We should be able to plan out things later.
**What happens to the turbopack api in napi bindings?**
Simply put, this **does not support turbopack in wasm**. Build works by
disabling turbopack (more notably, underlying dependency doesn't support
wasm) features. It is something to explore separately.
Closes PACK-2367
There is a branch at https://github.com/vercel/next.js/pull/61586 shows

### Description
This PR refactors existing `analysis/get-static-page-info`, moves over
most of parse / ast visiting logic into next-swc's rust codebase. By
having this, turbopack can reuse same logic to extract info for the
analysis. Also as a side effect, this removes JS side parse which is
known to be inefficient due to serialization / deserialization.
The entrypoint `getPageStaticInfo` is still in the existing
`get-page-static-info`, only for extracting / visiting logic is moved.
There are some JS specific context to postprocess extracted information
which would require additional effort to move into.
Closes PACK-2088
## What?
Skip postcss config resolving in node_modules for Turbopack. This
matches current Next.js on webpack closer as that only resolves the
postcss config from the project root. The additional feature Turbopack
has is that it can find a postcss config relative to the css being
compiled. This is useful for e.g. reducing the amount of overhead
certain postcss plugins that only have to run against a single file take
(i.e. Tailwindcss).
Depends on github.com/vercel/turbo/pull/7012 landing first.

### What?
This PR refactors organization for the rust side packages to build
`next-swc`.
### Why?
We had some historical legacy around package structures, have ambiguous
name for `core` / `next-core`. One contains swc transform visitor for
the next.js, and the other one is new for turbopack's core next.js
features. In addition to that, there was a package dependency chain
prevents to use `core` in the turobpack / next-swc both, so each time
porting a transformer into turbopack it requires to extract new
dependency to be imported in the both place.
PR touches its organization - while PR is large to touch various files,
the crux is summarized at
2cedd06ea5
:
1. `core` becomes `next-custom-transforms`, also this becomes an
agnostic pkg can be imported in turbopack / wasm / next-swc
2. simplify dependency chain to import next-custom-transforms, organized
as below
```mermaid
flowchart TD
C(next-custom-transforms) --> A(napi)
C(next-custom-transforms) --> B(wasm)
D(next-core) --> A(napi)
E(next-build) --> A(napi)
F(next-api) --> A(napi)
C(next-custom-transforms) --> D
D(next-core) --> F(next-api)
D(next-core) --> E(next-build)
```
`impl CustomTransformer` for the each transform still lives in
`next-core`, so turbopack specific dependency is isolated under
`next-core/build/api`.

### What?
Turbopack does not apply same transform for the react server components,
which makes missing lot of compilation error validation and custom
comments. PR refactors transform to be used in next-swc / turbopack
both, then apply it into turbopack.
There are still some of test cases are not passing, might need further
digging for the transform condition.

### What?
switch turbopack to use a single client components entrypoint for all
client components on a page for development. This aligns it with the
webpack behavior.
### Why?
compiling a separate entrypoint for every client component is pretty
expensive in regards of compilation, chunking, code generation, file
writing and number of requests.

### What?
Bump up turbopack which includes url rewrite related improvements. This makes `test/integration/url` test passes.
Note there are some lacking behavior around edge runtime + url behavior, it is being tracked in PACK-2014.

### What
Pairing with https://github.com/vercel/turbo/pull/6602, enables
ecma-related transform support in mdx. notably fixes test cases in
https://github.com/vercel/next.js/pull/58968 .
With turbopack side fix, still modularize imports are not being applied
as we limite it to .js* extension only. PR expands it to include mdx if
mdx is enabled. PR is failling until turbopack side fix lands.

### What?
We are experimenting with `lightningcss`. This is about replacing
`swc_css` with `lightningcss` in turbopack, and the main reason for this
is to reduce the maintenance burden.
But when I tried, it introduced several regressions, so I'm putting it
behind an experimental flag.
You can enable `lightningcss` mode for **turbopack** by adding a flag to
the next config file.
```js
/**
* @type {import('next').NextConfig}
*/
const nextConfig = {
experimental: {
useLightningcss: true,
},
}
module.exports = nextConfig
```
Note that this is only for turbopack because we were not using `swc_css`
for non-turbopack mode of next.js

This PR implements initial support for the `next/dynamic` in Turbopack,
more specifically resolving some hydration errors and other components
boot up cases.
Previously, turbopack had partial next/dynamic support via its own mode
(https://github.com/vercel/next.js/pull/56389/files#diff-e1af4f79cb88a73f819a25443d15ed4b1ffabcbb879256caa59b751fad46d7c4L68),
which does a transform against `next/dynamic` wrapped import to embed
dynamically resolvable chunk ids like
(ad42b610c2/packages/next-swc/crates/next-transform-dynamic/tests/fixture/wrapped-import/output-turbo-dev-server.js).
However, since next.js relies on static path to the chunks to the
dynamic import and passing those ids in between client-server to ensure
component load (and avoid hydration errors), it doesn't work out of the
box. This PR changes turbopack's behavior to closely mimic what current
next.js's webpack plugin does, by
1. Traverse the module graph, find out `dynamic(import())`
2. Generate chunks for those imports, creates a partial LoadableManifest
per each imports
3. Merge partial manifest into a single `react-loadable-manifest.json`
4. For the id, use static (Webpack mode) instead of dynamic so we can
embed it in `react-loadable-manifest` as well as next.js can use it to
pass it between server-client context.
I left a small comment to the implementation
(https://github.com/vercel/next.js/pull/56389/files#diff-bf12ed2c69d0bc89a06884779da4ae44967eb8becada031dea12bedef28e2622R155)
for the lifecycle of this feature in case to fix further.
This makes to pass most of the basic next-dynamic related integration
tests, except if the import have webpack specific features like
ad42b610c2/test/development/basic/next-dynamic/pages/dynamic/multiple-modules.js (L5).

### What?
Step 3 in our chunking refactors extracts ChunkItem::as_chunk into a new ChunkType trait. This new trait isn't useful yet, but will eventually allow us to collect ChunkItems of a similar type into a lists, and perform chunking over all similar items at once.
### Why?
In the end we want to avoid creating chunks from modules directly, but enforce everything going through the ChunkingContext to be chunked. This allows us to replace the existing chunking algorithm with a much more efficient one that avoid duplication between chunks in first place and doesn't require a post-chunking optimization.

### What?
The second step in our chunking refactoring, this removes our use of Module::as_chunk and Module::as_root_chunk. Instead, the only way to generate a chunk is directly from a root ChunkItem.
### Why?
In the end we want to avoid creating chunks from modules directly, but enforce everything going through the ChunkingContext to be chunked.

### What?
This change moves a few methods around.
Module::as_chunk is moved to ChunkItem::as_chunk as temporary intermediate state.
EcmascriptPlaceable::as_chunk_item is moved to ChunkableModule::as_chunk_item. This generalizes the concept of converting a Module into a ChunkItem
### Why?
This is the first step of refactoring the chunking. In the end we want to avoid creating chunks from modules directly, but enforce everything going through the ChunkingContext to be chunked. This allows us to replace the existing chunking algorithm with a much more efficient one that avoid duplication between chunks in first place and doesn't require a post-chunking optimization.

### What?
This implements Server Actions inside the new Turbopack next-api bundles.
### How?
Server Actions requires:
1. A `.next/server/server-reference-manifest.json` manifest describing what loader module to import to invoke a server action
2. A "loader" entry point that then imports server actions from our internal chunk items
3. Importing the bundled `react-experimental` module instead of regular `react`
4. A little 🪄 pixie dust
5. A small change in the magic comment generated in modules that export server actions
I had to change the magic `__next_internal_action_entry_do_not_use__` comment generated by the server actions transformer. When I traverse the module graph to find all exported actions _after chunking_ has been performed, we no longer have access to the original file name needed to generate the server action's id hash. Adding the filename to comment allows me to recover this without overcomplicating our output pipeline.

This constructs a general asset prefix (depending on if basePath and/or assetPrefix is defined), and sets it on Next's and Turbopack's chunking context.

### What?
Strip the relative path prefix (`_next/`) when generating the `PageLoaderAsset`. This is necessary because the page loader will internally use `__turbopack_load__`, which prepends the prefix back onto the path.
### Why?
Without this, we'd try loading `_next/_next/path/to/file.js`, because we'd prepend the prefix onto a path that already contains it.
### How?
When generating the page loader asset, we "proxy" the `OutputAsset` onto a path which has the prefix removed.
~~Depends on https://github.com/vercel/turbo/pull/5717~~
Closes WEB-1377
This implements a MVP of HMR. HMR works similarly as in turbopack-dev-server, but instead of going through the router to retrieve output assets, output assets are eagerly stored into a global hash map, and retrieved directly from there (see `VersionedContentMap`).
This will require some more glue on the Next.js side in order to handle:
* RSC headers;
* handling Turbopack subscriptiob HMR events from the Next.js WS server, proxying them to `hmr_events`, and sending back the stream of updates.
There's currently no way to evict deleted output assets, nor to communicate these events to the client. @sokra mentioned the `VersionedContentMap` could store a list of assets per entrypoint, instead of having a top-level flat map.

### What?
closes WEB-1301. To collect some information inside of rust binary, embed it as build-time constant. It supersedes existing target triple embedding as well.
This implements app pages and routes for the Nexturbo API.

This PR adds proof-of-concept support for the App Router to `next build
--experimental-turbo`.
It introduces a new way to generate Next.js manifests in Turbopack.
Currently, in dev, we pass proxy objects in lieu of manifests, and rely
on the entries to know which chunks they need loaded on the client.
However, this can't work for builds because it requires control over
Next.js rendering, which is not compatible with a Next->Turbo approach.
We would need to modify Next.js to support these "lazy" entries. So for
now, we add well-known assets (`NextDynamicAsset`,
`NextServerComponentAsset`, `NextClientReferenceAsset`, etc.) to the
graph, which will get picked up when walking it during asset processing.
This lets us collect all possible entries before chunking.
This two-step process (collecting all entries, then chunking them) is
also a good first step towards production chunking.
