Add autopilot-aware pre-commit warnings + post-commit driver reminder

- Pre-commit hook: warns when autopilot is enabled and non-terminal tasks exist
- Post-commit hook: after commit, prints non-terminal task summary if autopilot on
- Post-commit exits 0 always (informational only, never blocks)
- Both hooks read .agent.md to detect Autopilot: Enabled
