auto-github-contributor

Interactively pick a quick-win contribution in any GitHub repo — either a labeled issue ("good first issue", "help wanted", docs) or a repo-scan candidate (typo, missing tests, i18n gap, actionable TODO). Runs a TDD dev-loop, opens a PR via gh, and returns the PR URL. Use when the user wants to auto-contribute to an open-source project end-to-end. Trigger words: auto-contribute, open a PR for me, find a good first issue, contribute to <repo>.
