cookiecutters: Use ruff and uv. Simplify coverage.

- build: Add .python-version. Use coverage directly, instead of pytest-cov. Remove linters from dev requirements.
- ci: Use official coveralls action. Test on PyPy 3.10.
- chore: Switch to ruff and uv.

ci: Add pre-commit job to automerge workflow, for consistency
chore: Switch to pyproject.toml
