CI: Use uv exclusively

[amotl]

About

That's just maintenance. In this case, streamline the CI configuration for improved ergonomics and future proofing, see GH-605.

Details

• activate-environment: true of newer astral-sh/setup-uv@v7 is the killer feature here, which wasn't available before.
• Configuring cache-dependency-glob: pyproject.toml isn't needed, because the recipe already employs an excellent default configuration that includes this and other project metadata files.
• The adjustments in test_cli were needed because of a different PyPy version installed by setup-uv. This will yield a report to Astral maintainers, unrelated to this patch.

Walkthrough

The test_cli_version test was modified to validate only the final line of stdout output instead of the entire output, allowing additional leading content while ensuring version information is correctly displayed.

Changes

Cohort / File(s)	Summary
Test Enhancement tests/test_cli.py	Modified test_cli_version to parse stdout into non-empty trimmed lines and assert that the last line matches the version, replacing strict entire-output matching to permit extra leading content.

Poem

🐰 A humble test did change its way,
To check the version come what may,
Not rigid now, but smart and keen,
The final line is what we glean,
More flexible, our version's seen! ✨

PyPy as installed by GHA's actions/setup-python doesn't do that.
