Updates our Python interpreter discovery to conform to the rules
described in #2386, please see that issue for a full description of the
behavior. Briefly, we now will search for interpreters that satisfy a
requested version without stopping at the first Python executable.
Additionally, if retrieving information about an interpreter fails we
will continue to search for a working interpreter. We also add the
plumbing necessary to request Python implementations other than CPython,
though we do not add support for other implementations at this time.
A major internal goal of this work is to prepare for user-facing managed
toolchains i.e. fetching a requested version during `uv run`. These APIs
are not introduced, but there is some managed toolchain handling as
required for our test suite.
Some noteworthy implementation changes:
- The `uv_interpreter::find_python` module has been removed in favor of
a `uv_interpreter::discovery` module.
- There are new types to help structure interpreter requests and track
sources
- Executable discovery is implemented as a big lazy iterator and is a
central authority for source precedence
- `uv_interpreter::Error` variants were split into scoped types in each
module
- There's much more unit test coverage, but not for Windows yet
Remaining work:
- [x] Write new test cases
- [x] Determine correct behavior around executables in the current
directory
- _Future_: Combine `PythonVersion` and `VersionRequest`
- _Future_: Consider splitting `ManagedToolchain` into local and remote
variants
- _Future_: Add Windows unit test coverage
- _Future_: Explore behavior around implementation precedence (i.e.
CPython over PyPy)

## Summary
<!-- What's the purpose of the change? What does it do, and why? -->
Followup to #3624. Drops the native manylinux wheel in favor of the
statically linked musl one with a manylinux2014 tag.
<!-- How was it tested? -->

## Summary
Restore API-compatibility with pre-1.1.0 versions of the `zip` crate,
and pin the dependency to the 0.6 series, due to concerns discussed in
https://github.com/astral-sh/uv/issues/3642.
## Test Plan
```
cargo run -p uv-dev -- fetch-python
cargo test
```

## Summary
Fix#3439 by retagging the statically linked musl binary for
manylinux2014. This is the most conservative option;
the regular manylinux one could be removed as well, and I expect other
archs could probably do this as well.

## Test Plan
Testing on manylinux.

This is needed to include uv in manylinux, which has both the
musllinux_1_1 and musllinux_1_2 images.
## Summary
We are looking into including uv in the `pypa/manylinux` docker images,
so that cibuildwheel will be able to use it. But to do so, we need all
actively supported images to be able to take it, including
musllinux_1_1.
## Test Plan
The test was updated to make sure Alpine 3.12, which musllinux was based
on, can run uv.
The binary build does need to be triggered on this PR to make sure it
works. Ah,
5b6040184d/.github/workflows/build-binaries.yml (L15-L20)
is a good idea, nice.
Will need a followup to fill out the other platforms `pypa/manylinux`
supports for musllinux.

Separates Windows tests from the rest because it's a pain and drops the
`python-patch` feature from testing so we can use the GitHub Actions
Python versions which bootstrap in 0 seconds instead of 2 minutes.
## Summary
This PR adds system install tests to verify the behavior described in
#2798. It turns out this behavior _also_ affects Fedora and Amazon
Linux, we just didn't have the right conditions enabled (specifically,
you need to create the virtualenv with `python -m venv` to get these
symlinks), so the test suite was expanded to capture that.
The issue itself is also fixed by way of deduplicating the
`site-packages` entries.

A first step towards Python toolchain management in Rust.
First, we add a new crate to manage Python download metadata:
- Adds a new `uv-toolchain` crate
- Adds Rust structs for Python version download metadata
- Duplicates the script which downloads Python version metadata
- Adds a script to generate Rust code from the JSON metadata
- Adds a utility to download and extract the Python version
I explored some alternatives like a build script using things like
`serde` and `uneval` to automatically construct the code from our
structs but deemed it to heavy. Unlike Rye, I don't generate the Rust
directly from the web requests and have an intermediate JSON layer to
speed up iteration on the Rust types.
Next, we add add a `uv-dev` command `fetch-python` to download Python
versions per the bootstrapping script.
- Downloads a requested version or reads from `.python-versions`
- Extracts to `UV_BOOTSTRAP_DIR`
- Links executables for path extension
This command is not really intended to be user facing, but it's a good
PoC for the `uv-toolchain` API. Hash checking (via the sha256) isn't
implemented yet, we can do that in a follow-up.
Finally, we remove the `scripts/bootstrap` directory, update CI to use
the new command, and update the CONTRIBUTING docs.

Reproduced https://github.com/astral-sh/uv/issues/2941 and confirmed
fix.
We probably ought to have some ecosystem test coverage — this seems like
a good starting point we can extend to other projects in the future.
Following #2735 adds a system check that uses Homebrew. I think we were
never were actually using Homebrew's Python in the past, we were mislead
or something changed in the runners recently that broke it.
