The Gitea Actions runner has a corrupted cache for actions/setup-python@v5: the cloned worktree has unstaged changes and the runner can't pull refs/heads/v5 cleanly. As a result the cached dist/setup/index.js is missing and the step fails before any of our lint commands run. Pin to v4 (different cache key) so the runner clones a fresh, unmodified copy.
