Krzysztof kuhy Rudnicki a4876d84ec Speed up CI: uv installs, split pre-commit into mypy/pylint/rest
- pre-commit: drop the 28 s requirements.txt install (only
  dependency-freshness among the system hooks needs third-party code:
  pyyaml, packaging), run pre-commit directly instead of
  pre-commit/action, and split mypy and pylint into their own matrix
  jobs with per-group hook-env caches. Same hook set, same
  SKIP=free-days-interop (the rest group).
- Tests: uv with a cached wheel store for requirements.txt (pip took
  22 s), -q and -p no:sugar. No -n auto: the suite runs in ~0.5 s and
  measured ~1.2 s under pytest-xdist.
- free-days-interop (the critical path): build the freedays venv with
  uv instead of venv + pip (12 s).
