### What
Use `addDependency` to track the file path passed to
`next-metadata-route-loader`
NOTE: We cannot apply the `next-metadata-route-loader` directly to the
metatda convention source files, since the json file could be processed
by json loader (Related previous fix#62615)
### Why
Previously when we passed down the file path as argument to the loader,
which sort of breaking the caching of webpack as the actual resource
path is string, it's not tracked as a dependency. This change fixed the
bad caching issue of static metadata routes. Based on the above reason
we use `addDependency` here to track the dependency change
Closes NEXT-3521
Closes#65755
### What
Skip adding trailing slash for file pattern like same origin urls
### Why
Fixes#66635
Next.js will not append trailing slash for file like pattern urls when
`trailingSlash` is enabled. This PR aligns the behavior of the metadata
trailing slash appending with next-server route handling.

To allow us to incrementally adopt more comprehensive linting rules,
this pull request disables the previous behaviour of failing CI when any
warnings were discovered. Instead, this modifies the previous warnings
to be errors which will preserve the previous linting behaviour. As we
enable new lint rules, they can be added as warnings which will gently
nudge us towards fixing in related pull requests.
As discussed this adds handling to timeout at a max of 500ms for fetch
cache request and retries a max of 3 times due to network instability.
This also adds cache service tests and fixes a case we've been trying to
track down where we were seeing `undefined` cache URL values which made
debugging fetches tricky.
To assist with the development and testing of the new partial
prerendering (PPR) paradigm, this introduces a stop-gap solution to let
us verify issues with pages in preview and production environments if
enabled. When a Next.js app is built and ran with the
`__NEXT_EXPERIMENTAL_STATIC_SHELL_DEBUGGING=1` environment variable,
pages that have PPR enabled in production and preview environments can
have only their static shell served when accessed with a
`?__nextppronly=1` query parameter.
If your project is not using PPR, it will not change anything. If a page
is accessed in production or development with the query parameter but
PPR is not enabled, it will not change anything. Tests have been added
to validate that going forward.
### What
Optimizing the static generation for dynamic metadata routes
If you're not using `generateSitemaps()` or `generateSitemaps()`, you
don't need to change any file conventions.
If you're using multi sitemap routes, make sure the returned `id`
properties from `generateSitemaps()` don't need to contain `.xml`, since
we'll always append one for you.
Analyzing the exports of metadata routes and determine if we need to
make them as dynamic routes.
### Why
Previously, users are struggling with the multi routes of sitemap or
images.
For sitemap, the `.xml` extension in url doesn't get appended
consistently to the multi sitemap route between dev and prod.
For image routes, the generated image routes are always dynamic routes
which cannot get static optimized.
The reason is that we need to always generate a catch-all route (such as
`/icon/[[...id]]` to handle both single route case (e.g. without
`generateImageMetadata`, representing url `/icon`) or multi route (e.g.
with `generateImageMetadata`, representing url `/icon/[id]`), only
catch-all routes can do it. This approach fail the static optimization
and make mapping url pretty difficult as parsing the file to check the
module exports has to be done before it.
#### Benifits
For image routes urls, this approach could help on static generation
such as single `/opengraph-image` route can be treated as static, and
then it can get static optimized if possible.
**Before**: `/opengraph-image/[[...id]]` cannot be optimized
**After**: single route `/opengraph-image` and multi-route
`/opengraph-image/[id]` are both possible to be statically optimized
For sitemap, since we removed appending `.xml` for dynamic routes, it’s
hard for users to have `/sitemap.xml` url with dynamic route convention
`sitemap.js` . But users desire smooth migration and flexibility.
**Before**: In v15 rc we removed the `.xml` appending that `sitemap.js`
will generate url `/sitemap` makes users hard to migrate, as users need
to re-submit the new sitemap url.
**After**: Now we'll consistently generate the `.xml`. Single route will
become `/sitemap.xml`, and multi route will become `/sitemap/[id].xml`.
It's still better than v15 as the urls generation is consistent, no
difference between dev and prod.
Here's the url generation comparsion
#### Before
All the routes are dynamic which cannot be optimized, we only had a
hacky optimization for prodution build multi-routes sitemap routes
| | only default export | `export generateImageMetadata()` | `export
generateSitemaps()` |
| -- | -- | -- | -- |
| opengraph-image.js | /opengraph-image/[[...id]] |
/opengraph-image[[...id]]/ | /opengraph-image/[[...id]] |
| sitemap.js | /sitemap/[[...id]] | /sitemap/[[...id]] | dev:
`/sitemap/[[...id]]` prod: `/sitemap/[id]` |
#### After
Most of the single route will are to get statically optimized now, and
the multi-routes sitemap are able to get SSG now
| | only default export | `export generateImageMetadata()` | `export
generateSitemaps()` |
| -- | -- | -- | -- |
| opengraph-image.js | /opengraph-image | /opengraph-image/[id] | - |
| sitemap.js | /sitemap.xml | - | /sitemap/[id].xml |
Next.js will have less overhead of mapping urls, we can easily multiply
the urls generation simply based on file conventions.

### Why?
Importing `tailwind/tailwind.css` is not possible right now with
turbopack, and there's no reason it needs to be marked as external.
### How?
Closes PACK-3013
Fixes#64837
### What
Remove creating client proxy for each ESM export, instead for ESM we
create a CJS module proxy for itself and access the property with export
name as the actual export.
### Why
`proxy` is the module proxy that we treat the module as a client
boundary.
For ESM, we access the property of the module proxy directly for each
export.
This is bit hacky that treating using a CJS like module proxy for ESM's
exports,
but this will avoid creating nested proxies for each export. It will be
improved in the future.
Notice that for `next/dynamic`, if you're doing a dynamic import of
client component in server component, and trying to access the named
export directly, it will error. Instead you need to align the dynamic
import resolved value wrapping with a `default:` property (e.g. `{
default: resolved }`) like what `React.lazy` accepted.

During navigations, the `FlightDataPath` property from the server
response can be an array if there are multiple parallel routes (eg,
`children` and `slot`). When we apply server response to the router
cache, we might call `applyFlightData` for each segment path, which will
copy existing cache values and insert new ones depending on what
changed.
However, the `existingCache` argument that we pass to this function is
the cache at the start of the navigation. That means subsequent calls to
`applyFlightData` will reference the cache _before_ updates are made to
it. This will cause it to erroneously think it needs to lazy fetch for
missing data.

When checking which segment(s) need to be refreshed, we currently
compare the current page URL with the segment's refresh marker.
We should inspect the `mutable.canonicalUrl` value first since that's
the URL we're changing to, followed by `state.canonicalUrl` as a
fallback (indicating that there's no URL change pending). This is
because the server action handler will receive a redirect URL prior to
`location.pathname` being updated, so the router will incorrectly think
it needs to refresh the data for the page we're going to.
Closes NEXT-3500
This flag remained experimental because the IPC implementation didn't
play nicely with requests containing large payloads, due to it being
stringified as GET parameters. This branching logic also poses
challenges for some upcoming work related to detecting IO.
This removes the handling for the
`experimental.staticWorkerRequestDeduping` flag which we can revisit in
the future with a sounder approach. This also cleans up some of the IPC
server utilities as it wasn't in use anywhere else.

This PR fixes the same case mention in #66464. Instead of collecting all
values eagerly, here we merge fields (on any level of depth) of the same
value and skip methods. For example:
```ts
foo.bar
foo.bar.baz
qux.fn()
```
Previously we're (wrongly) collecting `[foo.bar, foo.bar.baz, qux.fn]`,
and now it will be just `[foo.bar, qux]`.
Merging of fields is critical for collecting methods correctly because
in theory we can't tell if an object member is a method or not:
```ts
data.push.call(data, 1)
// or inside a function that does the same:
doPush(data.push, data)
```
If we don't merge fields we'll collect `[data.push, data]` which still
fails.
### What & Why
Fixes NEXT-3498
Fixed loading shows up and disappear during client navigation, when you
defined `prefetch` is enabled and slow `generateMetadata` is defined. In
#64532, where in layout-router, we removed the place of infinite
suspense, adding it back so that the app can still remain suspensy
during navigation.
#### Behavior before fix
Prefetch -> Link Navigation -> Show `loading.js` -> RSC payload fetched
(no page content) -> the page content will display later when the
promise is resolved
#### Behavior after the fix
Prefetch -> Link Navigation -> Show `loading.js` -> RSC payload fetched
-> suspensy page content still triggering `loading.js` -> display the
resolved page content when the promise is resolved
