Subject: [PATCH] Add cache-suffix to setup-uv steps to avoid cache key
 collisions

Jobs with different `uv sync` dependency groups (e.g., `--group typing
--group test` vs `--all-groups`) computed identical cache keys since
GitHub Actions caches are immutable (first-writer-wins). Add distinct
`cache-suffix` values to each non-matrix job: mypy, deps, pylint,
pip-audit, and deps-update.
