Closes #19283
Closes #19277
Closes #19285

Previously, parsing a version like `3.14.5rc1` was rejected with
"not a valid Python download request" because the validation required
pre-releases to have a patch version of zero. However, python-build-standalone
now publishes release candidates for non-zero patch versions (e.g., 3.14.5rc1).

Add a `MajorMinorPatchPrerelease` variant to `VersionRequest` to retain the
patch component when parsing pre-release versions with a non-zero patch, and
update all match statements accordingly.

Fixes astral-sh#19283.
Verify that `uv python install 3.14.5rc1` succeeds, covering the regression
fixed in the previous commit.

The release candidate creates a python3.14 symlink since no prior 3.14
installation exists in the test context.

### [`v0.11.9`](https://github.com/astral-sh/uv/blob/HEAD/CHANGELOG.md#0119)

[Compare Source](astral-sh/uv@0.11.8...0.11.9)

Released on 2026-05-04.

This release includes a special release candidate for the next Python 3.14 patch release. Python 3.14 included a new garbage collection implementation, which reduced pause times but caused significant unexpected memory pressure in production environments. In 3.14.5 and 3.15, the previous garbage collection implementation will be restored.

We would greatly appreciate if you tested the 3.14.5rc1 version included in this release. The stable version is expected to be released soon and any feedback on potential issues would be helpful to the Python development team.

For more context, see the [announcement](https://discuss.python.org/t/reverting-the-incremental-gc-in-python-3-14-and-3-15/107014), [issue](python/cpython#148726), and [pull request](python/cpython#148720).
