build(deps): bump the python group with 2 updates

[dependabot]

Bumps the python group with 2 updates: uv and gevent.

Updates uv from 0.11.31 to 0.12.0

Release notes

Sourced from uv's releases.

0.12.0

Release Notes

Released on 2026-07-28.

Since we released uv 0.11.0 in March, we've accumulated changes that improve correctness, safety, and compatibility with specifications, but could break some workflows. This release contains those changes; many have been marked as breaking out of an abundance of caution.

We expect most users to be able to upgrade without making changes.

There are no breaking changes to the configuration of the uv build backend. If your [build-system] table includes an upper bound on uv_build, update it to allow uv_build 0.12, e.g., uv_build>=0.11.32,<0.13.

Breaking changes

• Define build systems by default with uv init (#19197)

  Projects created with uv init now declare a build system and are packaged by default. This was the default project layout all the way back in v0.3, but we found that the use of the hatchling build system was confusing to newcomers and consequently dropped use of a build system by default in v0.4. Since then, we've created our own build system (uv_build) with tight integration with uv and are excited to restore the default to a best-practice project layout.

  Previously, uv init example created an unpackaged layout containing main.py and a pyproject.toml without a build system. The project could declare dependencies but was not itself installed into its virtual environment.

  Now, uv init example defines a [build-system] using uv_build, places application source code in src/example, and includes a [project.scripts] entry named example. Defining a build system allows the project to be imported from tests or other code, installed as a dependency, and run as a command:

  $ uv init example
  $ cd example
  $ uv run example
  Hello from example!

  Existing projects are unaffected. Use uv init --no-package example to create the previous unpackaged layout without a build system.

  See the project creation documentation for more details.

  This stabilizes the packaged-init preview feature.

• Reject unsupported source distribution and wheel archive formats (#18927)

  PEP 625 requires source distributions to use .tar.gz archives. Previously, uv also accepted legacy formats such as .tar.bz2 and .tar.xz. Those formats are now rejected, including when referenced by an existing lockfile. Legacy .zip source distributions remain supported for backwards compatibility.

  Wheels and other ZIP archives can no longer contain entries compressed with bzip2, LZMA, or XZ. Entries must use the stored, DEFLATE, or zstd compression methods.

  Removing support for uncommon compression methods reduces uv's compression dependencies and the attack surface exposed when processing untrusted packages.

  You cannot opt out of this behavior. If you depend on a legacy source distribution that uses an unsupported format, we recommend rebuilding it as a .tar.gz archive and regenerating any lockfile containing references to the legacy archive.

• Reject wheel files that could replace the Python interpreter (#20748, #20749)

  uv already rejected wheel entry points named python, but case variants such as Python were still accepted. On case-insensitive filesystems, including common macOS and Windows setups, these entry points could overwrite the virtual environment's interpreter.

  Wheels could also place interpreter files in their .data/scripts directory or in paths such as .data/data/bin/python, bypassing the entry-point check and replacing the interpreter during installation.

  uv now rejects case-insensitive variants of reserved interpreter names and wheel data files that would be installed over an interpreter. This includes names such as Python, python.py, and Python.exe, along with other reserved interpreter names and their versioned variants.
