### What
When triggering an interception route that has a parent with dynamic
params, and then later going to "refresh" the tree, either by calling
`router.refresh` or revalidating in a server action, the refresh action
would silently fail and the router would be in a bad state.
### Why
Because of the dependency that interception routes currently have on
`FlightRouterState` for dynamic params extraction, we need to make sure
the refetch has the full tree so that it can properly extract earlier
params. Since the refreshing logic traversed parallel routes and scoped
the refresh to that particular segment, it would skip over earlier
segments, and so when the server attempted to diff the tree, it would
return an updated tree that corresponded with the wrong segment
(`[locale]` rather than `["locale", "en", "d]`).
Separately, since a page segment might be `__PAGE__?{"locale": "en"}`
rather than just `__PAGE__`, this updates the refetch marker logic to do
a partial match on the page segment key.
### How
This keeps a reference to the root of the updated tree so that the
refresh always starts at the top. This has the side effect of
re-rendering more data when making the "stale" refetch request, but this
is necessary until we can decouple `FlightRouterState` from interception
routes.

Currently we aren't detecting the draft mode case properly in
`unstable_cache` so the cache is unexpectedly being leveraged. This
ensures we bypass the cache for `unstable_cache` in draft mode the same
way we do for the fetch cache handling.

Both of these run on a schedule that is before the start of the day in

Closes NEXT-2904
Trying to submit a server action when JS is disabled (ie, no action
header in the request, and in the "progressively enhanced" case) for a
static resource results in a 405 error when deployed to Vercel. In the
absence of an action ID header, the request content-type is used to
signal that it shouldn't try and hit the static cache. However with
multipart/form-data, this will include the boundary. This updates the
matcher to consider a boundary string.

Previously, there was no check when a path was passed with the
--import-alias flag. Furthermore, the regex used before did not check
for possible invalid paths.
The current regex checks the following conditions:
- It must follow the pattern `<prefix>/*`
- The prefix cannot contain invalid characters for folders, such as:
(whitespaces, /, <, >, :, ", /, \, |, ? and *)

This introduces an experimental router flag (`experimental.staleTimes`)
to change the router cache behavior. Specifically:
```ts
// next.config.js
module.exports = {
experimental: {
staleTimes: {
dynamic: <seconds>,
static: <seconds>,
},
},
};
```
- `dynamic` is the value that is used when the `prefetch` `Link` prop is
left unspecified. (Default 30 seconds)
- `static` is the value that is used when the `prefetch` `Link` prop is
`true`. (Default 5 minutes)
Additional details:
- Loading boundaries are considered reusable for the time period
indicated by the `static` property (default 5 minutes)
- This doesn't disable partial rendering support, **meaning shared
layouts won't automatically be refetched every navigation, only the new
segment data**.
- This also doesn't change back/forward caching behavior to ensure
things like scroll restoration etc still work nicely.
Please see the original proposal
[here](https://github.com/vercel/next.js/discussions/54075#discussioncomment-6754339)
for more information. The primary difference is that this is a global
configuration, rather than a per-segment configuration, and it isn't
applied to layouts. (We expect this to be a "stop-gap" and not the final
router caching solution)

chunk

### What?
This fixes an issue where the `nonce` attribute isn't set on
`next/script` elements that has the `afterInteractive` (the default)
strategy resulting in `<link rel="preload" as="script"/>` tags without a
nonce.
### Why?
For apps that uses 3rd party scripts (or any script) with a nonce loaded
via `next/script` this is necessary unless you want them all to use
`beforeInteractive` which isn't super nice for performance.

### 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.
