## Summary
This PR enables users to mark a URL as an S3 endpoint, at which point uv
will sign requests to that URL by detecting credentials from the
standard AWS environment variables, configuration files, etc.
Signing is handled by the
[reqsign](https://docs.rs/reqsign/latest/reqsign/) crate, which we can
also use in the future to sign requests for other providers.

Add an incompatibility that lets pubgrub skip of marker packages when
the base package already has an incompatible version to improve the
error messages (https://github.com/astral-sh/uv/issues/15199).
The change is also a small perf improvement. Overall this should be able
to improve performance in slow cases by avoiding trying proxy package
versions that are impossible anyway, for a (ideally very small cost) for
tracking the additional incompatibility and tracking the base package
for each proxy package.
```
$ hhyperfine --warmup 2 "uv pip compile --universal scripts/requirements/airflow.in" "target/release/uv pip compile --universal scripts/requirements/airflow.in"
Benchmark 1: uv pip compile --universal scripts/requirements/airflow.in
Time (mean ± σ): 145.5 ms ± 3.9 ms [User: 154.7 ms, System: 140.7 ms]
Range (min … max): 139.2 ms … 153.4 ms 20 runs
Benchmark 2: target/release/uv pip compile --universal scripts/requirements/airflow.in
Time (mean ± σ): 128.7 ms ± 5.5 ms [User: 141.9 ms, System: 137.3 ms]
Range (min … max): 121.8 ms … 142.0 ms 23 runs
Summary
target/release/uv pip compile --universal scripts/requirements/airflow.in ran
1.13 ± 0.06 times faster than uv pip compile --universal scripts/requirements/airflow.in
```
This implementation is the basic version: When we see a proxy
`foo{...}>=x,<y` we add a dependency edge `foo{...}>=x,<y` ->
`foo>=x,<y`. There are several way to extend this, which likely help
more with performance than with error messages.
One idea is that if we see `foo{...}>=x,<y` but we already made a
selection for `foo==z` outside that range, we can insert a dependency
`foo{...}!=z` -> `foo!=z`. This avoids trying any version of the proxy
package except the version that matches our previous selection.
Another is that if we see a dependency `foo>=x,<y`, we also add
`foo{...}>=x,y` -> `foo>=x,<y`. This allows backtracking beyond `foo`
immediately if all version of `foo{...}>=x,<y` are incompatible, since
`foo{...}>=x,<y` incompatible -> `foo>=x,<y` incompatible -> the package
that depended of `foo>=x,<y` is incompatible.
The cost for each of these operations is tracking an additional
incompatibility per virtual package. An alternative approach is to only
add the incompatibility lazily, only when we've tried several version of
the virtual package already. This needs to be weighed of with the better
error messages that the incompatibility gives, we unfortunately have
only few large reference examples.

## Summary
In the process of making a different change, I noticed that we parse
this during source discovery, throw it away, then parse it again later.
## Summary
If the target for `uv pip compile` is a `pyproject.toml` in a
subdirectory, we won't have loaded the credentials when we go to lower
(since it won't be loaded as part of "configuration discovery"). We now
add those indexes just-in-time.
Closes https://github.com/astral-sh/uv/issues/15362.
The initial motivation for this change was that we were using both the
`windows`, the `window_sys` and the `windows_core` crate in various
places. These crates have slightly unconventional versioning scheme
where there is a large workspace with the same version in general, but
only some crates get breaking releases when a new breaking release
happens, the others stay on the previous breaking version. The `windows`
crate is a shim for all three of them, with a single version. This
simplifies handling the versions.
Using `windows` over `windows_sys` has the advantage of a higher level
error interface, we now get a `Result` for all windows API calls instead
of C-style int-returns and get-last-error calls. This makes the
uv-keyring crate more resilient.
We keep using the `windows_registry` crate, which provides a higher
level interface to windows registry access.
uv currently panics with a stack overflow when requirements or
constraints are recursively included. Instead, we ignore files we have
already seen. The one complexity here is that we have to track whether
we're in a requirements inclusion or in a constraints inclusion, to
allow including a file separately for requirements and for constraints,
and to handle `-r` inside or `-c` (which we treat as constraints too).
Fixes#15650
## Summary
This PR allows pyx to send down hashes for zstandard-compressed
tarballs. If the hash is present, then the file is assumed to be present
at `${wheel_url}.tar.zst`, similar in design to PEP 658
`${wheel_metadata}.metadata` files. The intent here is that the index
must include the wheel (to support all clients and support
random-access), but can optionally include a zstandard-compressed
version alongside it.
## Summary
This PR adds support for pyx to `uv auth login`, `uv auth logout`, and
`uv auth token`. These are generic uv commands that can be used to store
credentials for arbitrary indexes and other URLs, but we include a
fast-path for pyx that initiates the appropriate login or logout flow.
We're not sure what the best way to expose the native store to users is
yet and it's a bit weird that you can use this in the `uv auth` commands
but can't use any of the other keyring provider options. The simplest
path forward is to just not expose it to users as a keyring provider,
and instead frame it as a preview alternative to the plaintext uv
credentials store. We can revisit the best way to expose configuration
before stabilization.
Note this pull request retains the _internal_ keyring provider
implementation — we can refactor it out later but I wanted to avoid a
bunch of churn here.
Adds locking of the credentials store for concurrency safety. It's
important to hold the lock from read -> write so credentials are not
dropped during concurrent writes.
I opted not to attach the lock to the store itself. Instead, I return
the lock on read and require it on write to encourage safe use. Maybe
attaching the source path to the store struct and adding a `lock(&self)`
method would make sense? but then you can forget to take the lock at the
right time. The main problem with the interface here is to write a _new_
store you have to take the lock yourself, and you could make a mistake
by taking a lock for the wrong path or something. The fix for that would
be to introduce a new `CredentialStoreHandle` type or something, but
that seems overzealous rn. We also don't eagerly drop the lock on token
read, although we could.
