Persona

- Add git policy section in system prompt (gadget.py): no auto git add/commit
- Add policy warning in git_operation tool description (coder.py)
- LLM must ask user before running git add or git commit
- Safe commands (git status, git diff, git log) can run without asking
- When user asks to commit: show changes first, then wait for confirmation
