Supervisor Recovery Test

Tests the complete supervisor-driven auto-recovery flow:
1. Start a pipeline
2. Force iteration_limit to trigger abort
3. Verify GAMMA synthesizes proposals before handoff
4. Verify supervisor spawns recovery pipeline
5. Verify recovery pipeline loads handoff with resume message
6. Track all retries until success or max failures

Run with: python3 tests/test_supervisor_recovery.py
Requires: UI server running on localhost:3000
