To help detect when newly added/changed assertions are flakey this adds
a job to our build and test workflow to re-run them 3 times. If the
changed test is an E2E test it will re-run in both development and
production mode to ensure it's not flakey specifically in one of those
modes.
Test run with changed test can be seen here

### What?
Removed "When `prefetch` is set to `false`, prefetching will still occur
on hover." from prefetch field documentation.
### Why?
This behaviour no longer happens when using the app router. It's really
misleading, since it creates the assumption that this behaviour always
exists.
<!--
### How?
Closes NEXT-
Fixes #

Co-authored-by: JJ Kasper <jj@jjsweb.site>
### What & Why
There was some code added in the catch-all route normalization that
doesn't seem to make sense -- it was checking if the provided `appPath`
depth was larger than the catch-all route depth, prior to inserting it.
But it was comparing depths in an inconsistent way (`.length` vs
`.length - 1`), and the catch all path was also considering the `@slot`
and `/page` suffix as part of the path depth.
This means that if you had a `@modal/[...catchAll]` slot, it wouldn't be
considered for a page like `/foo/bar/baz`, because `/foo/bar/baz`
(depth: 4 with the current logic) and `/@modal/[...catchAll]/page`
(depth: 3 with the current logic) signaled that the `/foo/bar/baz` route
was "more specific" and shouldn't match the catch-all.
I think this was most likely added to resolve a bug where we were
inserting optional catch-all (`[[...catchAll]]`) routes into parallel
slots. However, optional catch-all routes are currently unsupported with
parallel routes, so this feature didn't work properly and the partial
support introduced a bug for regular catch-all routes.
### How
This removes the confusing workaround and skips optional catch-all
segments in this handling. Separately, we can add support for optional
catch-all parallel routes, but doing so will require quite a bit more
changes & also similar handling in Turbopack. Namely, if have a
top-level optional catch-all, in both the Turbopack & current Webpack
implementation, that top-level catch-all wouldn't be matched. And if you
tried to have an optional catch-all slot, in both implementations, the
app would error with:
> You cannot define a route with the same specificity as a optional
catch-all route ("/" and "/[[...catchAll]]")
because our route normalization logic does not treat slots specificity
differently than pages.
**Note**: This keeps the test that was added when this logic was first
introduced in #60776 to ensure that the case this was originally added
for still passes.
Fixes#62948
Closes NEXT-2728
## What?
This test currently causes others to fail. Trying adding a skip for this
to see if other issues come up before porting it to be isolated:
```
● Test suite failed to run\n\n The name `source-map` was looked up in the Haste module map. It cannot be resolved, because there exists several different files, or packages, that provide a module for that particular name and platform. The platform is generic (no extension).

### What?
Adds safe traversal to rewrite `has` items in a certain new
(`isInterceptionRouteRewrite()` added in the v14.2.0 canaries) check to
the rewrite routes.
### Why?
The new check assumed that all `has` arrays had at least one item, when
previously Next.js accepted rewrites with empty `has`. Adding safe
traversal doesn't negatively impact the check, as the check only needs
rewrites with the first item.

### How?
Closes PACK-2527
### What
Strip the search query for the `urlPathname` passed down to metadata
handling.
### Why
This is because the `urlPathname` from `staticGenerationStore` contains
query, so it will contain `?rsc` query for client navigation, which lead
to the relative path canonical url (e.g. `./`) will have the search
query along with it. This PR is to remove that and make sure always uses
pathname.
Reported by @pacocoursey
Closes NEXT-2963
### What & Why
When an RSC triggers `navigate` after the shell has already been sent to
the client, a meta tag is inserted to signal to the browser it needs to
perform an MPA navigation. This is primarily used for bot user agents,
since we wouldn't have been able to provide a proper redirect status
code (since it occurred after the initial response was sent).
However, the router would trigger a SPA navigation, while the `<meta>`
tag lagged to perform an MPA navigation, resulting in 2 navigations to
the same URL.
### How
When the client side code attempts to handle the redirect, we treat it
like an MPA navigation. This will suspend in render and trigger a
`location.push`/`location.replace` to the targeted URL. As a result,
only one of these navigation events will win.
Fixes#59800Fixes#62463
Closes NEXT-2952
Closes NEXT-2719
Currently, the encryption key for Server Actions is generated during the
manifest creation. This PR moves it to be in the same position as the
build ID generation, and we will later leverage that key for other use
cases.
Closes NEXT-2959
When a server action performs a redirect, we currently initiate a `HEAD`
request to the targeted URL to verify if it has a proper RSC response.
If it does, it then invokes a GET and streams the response. This leads
to an extra request to the server which can be costly and poor for
performance. If the `GET` returns an invalid RSC response, we'll discard
the response. The client router will also see the invalid response which
will signal that it needs to perform an MPA navigation to the targeted
URL.

Closes NEXT-2956
### What
Supports partial `get-page-static-info` in turbopack. Since turbopack
doesn't have equivalent place to webpack's ondemandhandler, it uses
turbopack's build time transform rule instead.
As noted, this is partial implementation to pagestatic info as it does
not have existing js side evaluations. Assertions will be added
gradually to ensure regressions, for now having 1 assertion for
getstaticparams.
Closes PACK-2849
### What
When calling `revalidatePath` or `revalidateTag` in a server action for
an intercepted route with dynamic segments, the page would do a full
browser refresh.
### Why
When constructing rewrites for interception routes, the route params
leading up to the interception route are "voided" with a
`__NEXT_EMPTY_PARAM__` demarcation. When it comes time to look up the
values for these dynamic segments, since the params aren't going to be
part of the URL, they get matched via `FlightRouterState`
([ref](d67d658ce7/packages/next/src/server/app-render/app-render.tsx (L153-L201))).
The `shouldProvideFlightRouterState` variable only passes it through for
RSC requests; however, since the server action will perform the action &
return the flight data in a single pass, that means the updated tree
from the server action isn't going to receive the `FlightRouterState`
when constructing the new tree. This means the old tree will have a
`["locale", "en", "d"]` segment, and the new tree from the server action
will have `"[locale]"`. When the router detects this kind of segment
mismatch, it assumes the user navigated to a new root layout, and
triggers an MPA navigation.
### How
This unconditionally provides the `FlightRouterState` to
`makeGetDynamicParamFromSegment` so that it can properly extract dynamic
params for interception routes. We currently enforce interception routes
to be dynamic due to this `FlightRouterState` dependency.
Fixes#59796
Closes NEXT-2079
`applyRouterStatePatchToTree` had been refactored to support the case of
not skipping the `__DEFAULT__` segment, so that `router.refresh` or
revalidating in a server action wouldn't break the router. (More details
in this #59585)
This was a stop-gap and not an ideal solution, as this behavior means
`router.refresh()` would effectively behave like reloading the page,
where "stale" segments (ones that went from `__PAGE__` -> `__DEFAULT__`)
would disappear.
This PR reverts that handling. The next PR in this stack (#63608) adds
handling to refresh "stale" segments as well.
Note: We expect the test case that was added in #59585 to fail here, but
it is re-enabled in the next PR in the stack.
Note 2: #63608 was accidentally merged into this PR, despite being a
separate entry in the stack. As such, I've copied the issues from that
PR into this one so they can be linked. See the notes from that PR for
the refresh fix details.

## 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.

### 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.
