### What?
When there's a parallel route adjacent to a tree that has no page
component, it's treated as an invalid entry in `handleAppPing` during
dev HMR, which causes an infinite refresh cycle
### Why?
In #51413, an update was made to `next-app-loader` to support layout
files in parallel routes. Part of this change updated the parallel
segment matching logic to mark the parallel page entry as `[
'@parallel', [ 'page$' ] ]` rather than `[ '@parallel', 'page$' ]`.
This resulted in `handleAppPing` looking for the corresponding page
entry at `client@app@/@parallel/page$/page` (note the `PAGE_SEGMENT`
marker) rather than `client@app@/@parallel/page`, causing the path to be
marked invalid on HMR pings, and triggering an endless fastRefresh.
### How?
A simple patch to fix this would fix this is to update `getEntryKey` to
replace any `PAGE_SEGMENT`'s that leak into the entry which I did in
59a972f53339cf6e444e3bf5be45bf115a24c31a.
The other option that's currently implemented here is to only insert
PAGE_SEGMENT as an array in the scenario where there isn't a page
adjacent to the parallel segment. This is to ensure that the
`parallelKey` is `children` rather than the `@parallel` slot when in
[`createSubtreePropsFromSegmentPath`](59a972f533/packages/next/src/build/webpack/loaders/next-app-loader.ts (L298)).
This seems to not cause any regressions with the issue being fixed in
51413, and also solves this case, but I'm just not 100% sure if this
might break another scenario that I'm not thinking of.
Closes NEXT-1337
Fixes#51951
### What?
Interception route rewrites are not properly parsing catch-all segments,
which leads to "missing parameter name" errors when passed to
`pathToRegexp`.
### Why?
The existing `toPathToRegexpPath` function ignores `...` and keeps it as
part of the regexp path. This means `pathToRegexp` will attempt to
handle `/foo/bar/:...baz` and `/foo/bar/:[...baz]` rather than
`/foo/bar/:baz*`
### How?
The regex used for matching the path was updated to support the dynamic
optional segment, and then we special case catch-all segments
Fixes#51784
---------
### What?
Paths with interception markers adjacent to dynamic segments are not correctly parsed, which leads to the path match logic failing.
### Why?
`getParametrizedRoutes` checks for brackets but isn't expecting to receive an interception marker. For example, a path of `/photos/(.)[author]/[id]` results in the following regex:
`/^\/photos\/\(\.\)\[author\]\/([^/]+?)(?:\/)?$/`
This will not match a path of `/photos/(.)zack/1` since it retained the `[author]` brackets.
`getSegmentParam` has a similar issue when getting values for path params, though we can just skip the interception markers and go straight to the params.

Fixes#48143Fixes#49614

follow up on #51413 where I kinda forgot to support parsing layout files in sub routes in a parallel segment.
This should fix it by making sure that we check at all level of the app loader tree and by creating an implicit inner `children` for all parallel slot
link NEXT-1301
This PR fixes a bug in which the layout files were not picked up if they were direct children of a parallel route slot.
Note: there's a bunch of other files that I've used for debugging that are not used for the test but I'm leaving them for future me.

## What?
Removes `experimental.appDir` this was leftover from when I flipped the
switch.
Kept the config file as in the future we might add future flags and
such. It also helps that it has the types comment included so you always
get types.

This PR fixes parallel routes navigation with `prefetch={false}`. This
was broken because the optimistic tree created when navigating with
prefetching disabled resulted in a state where the router tree was
expecting an incorrect node to be rendered and suspended until the
imaginary data arrived.
The fix consists of updating the method that creates the optimistic tree
in order to bailout of the optimistic tree creation when there are
multiple parallel routes for the current node.

This PR fixes a bug with interception where the rewritten path passed an
incorrect segment data on production, resulting in a 404.
The fix consists of moving the rewrite pre-processing step that rewrites
the dynamic segment from the originating path to when we actually
generate the rewrite. This is needed because that step does not run on
production. Now it does and signals correctly to the app-render that the
value for the segment can be determined from the path.
Also enables prod testing, which I had forgotten to enable.

This PR fixes issues where rendering a new parallel route would reset
the scroll state of the page. This would be very apparent if you
scrolled down the page and opened a modal in a parallel route.
After a bit of investigating, I found out that the scroll behaviour
worked like this:
- after a navigation, we say to the router that we should auto-scroll if
possible
- but we don't specify which node of the tree should scroll
- so what happened is that the first router node to run the auto-scroll
effect would steal the auto-scroll, even though it might have been
destined for another node
The fix consists of
- when we received the flight patch, we compute all new segment paths
that will be rendered and add them to the scroll ref
- when the router says that we should autoscroll, the autoscroll
components will now read those paths and compare them with their segment
path and if yes, they will autoscroll

This PR adds a new marker for intercepting siblings routes + adds some
validation to intercepting routes ( you shouldn't use (..) at the top
level!)
also fixes a bug with any interception from `/` when navigating from a
child route
the new marker, `(.)`, makes it easier to model cases like
```
/profile/[id]
/profile/[id]/photos/[id]/
```
With the current syntax available, you’d need to do:
```with (..):
/profile/[id]/(..)[id]/photos/[id]
with (...):
/profile/[id]/(...)profile/[id]/photos/[id]
with (..)(..):
/profile/[id]/(..)(..)profile/[id]/photos/[id]
```
now, with (.)
```
/profile/[id]/(.)photos/[id]
```

This PR basically adds support for processing multiple router payloads.
Previously we were only handling one payload at a time but now that we
introduced parallel routes, we need to be able to render and return
separate parts of the layout separately.
Before, the single payload was generated in a DFS manner: we traversed
the router state and rendered the first segment of the tree that we
found needed rendering. In practice, this meant that we could miss
adjacent segments that might need to be re-rendered as well.
Now, we iterate all branches of the tree and return an array of flight
patches to be applied on the client correctly.

This PR makes the parent layout of parallel routes re-render when the
parallel route segments are different or when either of them has a
refetch marker.
Example:
```
.
└── app/
├── page.ts
├── layout.ts
├── foo/
│ └── page.ts
└── @modal/
├── default.js
└── foo/
└── page.ts
```
Here if you navigated to `/foo` from `/`, `@modal/foo/page` would never
get re-rendered because the tree would only re-render from
`foo/page.ts`.
This PR adds a check that checks the router state on navigation to see
if the parallel route segments diverge on navigation. Here we would be
checking that `@modal/default` is different from `@modal/page` so we
would re-render.
Also added some logic to make sure that refetch routes are processed
first when handling parallel routes.

The first implementation had limitation wrt to static routes so this is
a "simpler" approach to making interception work. This also fixes a few
bugs.
In this PR:
- changed the computation of the referrer route to now live on the
client state, since it's the only place where you can accurately keep
track of that. One router state was not sufficient, we needed a delta of
two states to guess which route had changed when having parallel routes
in the tree.
- uses rewrites as the basis for interception now instead of route
handlers, this means that we have to do some sketchy logic to make the
rules work since they only handle regexes whereas we have
`path/like/[this]`
- dev server now reloads rewrites as well when needed

This ensures we prefix the dynamic route params in the query so that
they can be kept separate from actual query params from the initial
request.
Fixes: https://github.com/vercel/next.js/issues/43139
This PR implements the route intercepting feature from [the layouts
RFC](https://nextjs.org/blog/layouts-rfc#intercepting-routes).
You can use route interception by adding these special markers,
`(..),(...) or (..)(..)` to your segment definition, i.e. by creating a
page with this path: `/foo/bar/(..)baz/page.ts`.
Changes in this PR:
- added a new kind of route handlers to support intercepting routes
- added a "referrer" concept that is derived from the client router
state on navigation, where we try to guess which URL you were on before
- added some units tests
- updated the renderer to allow for overrides when the path params don't
include the current dynamic param, so we rely on the passed router state
to create it

### What?
This PR is another part of making parallel routes viable!
- enables some of the tests, partially only in dev (build fails because
the intersection routes are not implemented)
- introduces a new type of special file: a `default` file that can be
added to any segment, next to `page` etc, that will act as the
default/placeholder when a layout does not match
- this also fixes bugs when navigating within parallel routes

Added tests:
- Add tests for interception+parallel and interception
- Add test for parallel route tab bar
- Add test for back/forward navigation on parallel routes
Core changes:
- Updated handling of parallel route matcher `@` to produce the correct
router tree
- Fixed global-error resolving, it was resolving from the `page.js` on
each level. It should only live next to the root layout only, so now it
resolves when it finds the root layout.
- `applyRouterStatePatchToTree` now merges the levels of the original
tree and the patch. This ensures parallel routes that are not affected
by the response from the server are not removed from the tree.
- Ensure cache nodes are not removed when they're not affected by tree
patch, this ensures parallel route cache nodes will not be removed when
navigating.
Other changes:
- Added launch app-dir build to launch.json for vscode debugger
