I think overall it's not appropriate to add Vercel-specific caveats to
these guides because they make it look like they're upselling Vercel.
I've edited to emphasize the self-hosting condition instead, from which
one should be able to infer it doesn't apply to Vercel.

Small follow-up to #86591.

We don't need to recreate the server module map proxy every time we set
the manifests singleton. Instead, we can just update the underlying
server actions manifest, and the server module map can read the current
manifest from the singleton.
…atic import) (#86485)

In a previous PR #73184 the `?dpl`
query string was added to local images from static imports but not to
images without the static import.

This was a subtle change based on malte's PR review comment here:
#73184 (comment)

However, I can't think of reason why we should differentiate these two
since they are both related to the current deployment (as opposed to
remote images which live outside the deployment).

Furthermore, this string matching is causing microfrontends to fail to
add the `?dpl` because they have a path prefix and thus fail skew
protection.

So this PR fixes both problems by loosening the string matching to look
for src images that start with `/`.
This auto-generated PR updates the development integration test manifest used when testing Rspack.

Add helpers for using bincode with various commonly-used foreign types that do not implement `bincode::Encode`/`bincode::Decode`. We can't implement the bincode traits on these types ourselves because of the orphan rules.

This is pulled out of #85878 to make it easier to review.

This depends on my fork of bincode here: https://github.com/bgw/bincode/commits/bgw/patches/
Specifically, the `with =` attribute I added here: bgw/bincode@4103717

This behaves like the serde equivalent: https://serde.rs/field-attrs.html#with

I am working on trying to get the changes with the bincode fork upstreamed. I submitted a bugfix (bgw/bincode@9247286) via email to the maintainer to start. Upstream is hosted at https://git.sr.ht/~stygianentity/bincode and my fork there is at https://git.sr.ht/~bgw/bincode .
We (unsurprisingly) spend a lot of time encoding `Rope`s. Most of this is in `memcpy`ing the data out of the rope (not easy to optimize), but there's some cloning of refcounted `Bytes` containers here that can be easily avoided.

Yes, `Bytes`​ is refcounted, but updating refcounts isn't free, and it matters because this is a hot codepath.

This is too small to show up on any top-line measurement (<1%) of total time, but should still be an improvement.
