## Summary
This fixes https://github.com/astral-sh/uv/issues/12426 which helps use
a more accurate arg name in the help output.
## Test Plan
I didn't test it locally, @charliermarsh gave me guidance on what to
change so I looked around that file for another example of `value_name`
and repeated what I saw. I kept it formatted to 1 line based on it not
being a long line. The other example of `value_name` had everything on
separate lines because there were a bunch of parameters passed in.

## Summary
This PR modifies the requirement source entities to store a (new)
container struct that wraps `IndexUrl`. This will allow us to store
user-defined metadata alongside `IndexUrl`, and propagate that metadata
throughout resolution.
Specifically, I need to store the "kind" of the index (Simple API vs.
`--find-links`), but I also ran into this problem when I tried to add
support for overriding `Cache-Control` headers on a per-index basis: at
present, we have no way to passing around metadata alongside an
`IndexUrl`.
Match the module name to its module directory with potentially different
casing.
For example, a package may have the dist-info-normalized package name
`pil_util`, but the importable module is named `PIL_util`.
We get the module name either as dist-info-normalized package name, or
explicitly from the user. For dist-info-normalizing a package name, the
rules are lowercasing, replacing `.` with `_` and replace `-` with `_`.
Since `.` and `-` are not allowed in module names, we can check whether
a directory name matches our expected module name by lowercasing it.
Fixes#12187

## Summary
In general, we merge `--find-links` entries into each index. If a
package is pinned to an index, though, it seems surprising (and wrong)
that we'd ever select a distribution from `--find-links`. This PR
modifies the provider to ignore `--find-links` for any explicitly pinned
packages.
Allows `uv python list <request>` to filter the installed list. I often
want this and it's not hard to add.
I tested the remote download filtering locally (#12381 is needed for
snapshot tests)

## Summary
I want to use the flat index client from within the registry client, so
making them both depend on the same underlying primitives rather than
having the flat index client depend on the registry client.
## Summary
We respect `--exclude-newer` during resolution, but we weren't applying
it to individual _files_ when writing the lockfile. As a result, if
wheels were added to a distribution after its initial release, we'd end
up including them in the lockfile, even if they were uploaded after the
`--exclude-newer` date.
Closes https://github.com/astral-sh/uv/issues/12296.
## Summary
It's possible that the PyTorch version the user depends on isn't in the
latest index. These indexes are equally trusted, so we should override
the policy.
Closes#12357.

## Summary
<!-- What's the purpose of the change? What does it do, and why? -->
This fixes a case described in #12333, where trailing comments in
dependencies can be unexpectedly shifted when a new dependency is added.
Fixes#12333.
## Test Plan
<!-- How was it tested? -->
`cargo test` (Added a snapshot test)
## Summary
Resolves#11794.
When `uv python find` is given a `--script` option, either the existing
environment for that script or the Python executable that would be used
to create it will be returned. If neither are found, the command exits
with exit code 1.
`--script` is incompatible with all other options to the same command.
## Test Plan
Unit tests.
## Summary
This crate is for standards-compliant types, but this is explicitly a
type that's custom to uv. It's also strange because we kind of want to
reference `IndexUrl` on the registry type, but that's in a crate that
_depends_ on `uv-pypi-types`, which to me is a sign that this is off.
There was a bug where `UV_MANAGED_PYTHON` and `UV_NO_MANAGED_PYTHON`
only accepted `true` or `false`. This switches to the boolish value
parser for those flags.
Closes#12336
## Summary
Fixes the failing `cache_prune::prune_unzipped` test that was causing CI
failures in my other PR (#12328) and others like PR #12327.
The error message format changed to show a specific version constraint
(`iniconfig<=2.0.0`) rather than the generic 'all versions' message.
This PR updates the test to expect the new, more specific error message.
## Test Plan
Ran `cargo test -p uv cache_prune::prune_unzipped` to verify the test
now passes.
Previously, we required a username to perform a fetch from the keyring
because the `keyring` CLI only supported fetching password for a given
service and username. Unfortunately, this is different from the keyring
Python API which supported fetching a username _and_ password for a
given service. We can't (easily) use the Python API because we don't
expect `keyring` to be installed in a specific environment during
network requests. This means that we did not have parity with `pip`.
Way back in https://github.com/jaraco/keyring/pull/678 we got a `--mode
creds` flag added to `keyring`'s CLI which supports parity with the
Python API. Since `keyring` is expensive to invoke and we cannot be
certain that users are on the latest version of keyring, we've not added
support for invoking keyring with this flag. However, now that we have a
mode that says authentication is _required_ for an index (#11896), we
might as well _try_ to invoke keyring with `--mode creds` when there is
no username. This will address use-cases where the username is
non-constant and move us closer to `pip` parity.
This addresses a small part of #12280, namely when you have
`authenticate` set to `always`, it will output a distinct error message
for the case where you have a username but are missing a password.
## Summary
This is a prototype that I'm considering shipping under `--preview`,
based on [`light-the-torch`](https://github.com/pmeier/light-the-torch).
`light-the-torch` patches pip to pull PyTorch packages from the PyTorch
indexes automatically. And, in particular, `light-the-torch` will query
the installed CUDA drivers to determine which indexes are compatible
with your system.
This PR implements equivalent behavior under `--torch-backend auto`,
though you can also set `--torch-backend cpu`, etc. for convenience.
When enabled, the registry client will fetch from the appropriate
PyTorch index when it sees a package from the PyTorch ecosystem (and
ignore any other configured indexes, _unless_ the package is explicitly
pinned to a different index).
Right now, this is only implemented in the `uv pip` CLI, since it
doesn't quite fit into the lockfile APIs given that it relies on feature
detection on the currently-running machine.
## Test Plan
On macOS, you can test this with (e.g.):
```shell
UV_TORCH_BACKEND=auto UV_CUDA_DRIVER_VERSION=450.80.2 cargo run \
pip install torch --python-platform linux --python-version 3.12
```
On a GPU-enabled EC2 machine:
```shell
ubuntu@ip-172-31-47-149:~/uv$ UV_TORCH_BACKEND=auto cargo run pip install torch -v
