frankbria 5e1d8734b1 Add Ralph for Claude Code - autonomous AI development loop
Features:
- Intelligent exit detection (knows when project is done)
- Test limiting (enforces 20% rule to prevent busy work)
- Rate limiting with graceful API usage management
- Live monitoring dashboard with real-time progress
- Auto-generated documentation every 10 iterations
- Specification-driven development approach

Based on Geoffrey Huntley's Ralph technique, adapted for Claude Code.
