🎉 Initial commit: Lightning Policy Manager

Advanced Lightning Network channel fee optimization system with:

✅ Intelligent inbound fee strategies (beyond charge-lnd)
✅ Automatic rollback protection for safety
✅ Machine learning optimization from historical data
✅ High-performance gRPC + REST API support
✅ Enterprise-grade security with method whitelisting
✅ Complete charge-lnd compatibility

Features:
- Policy-based fee management with advanced strategies
- Balance-based and flow-based optimization algorithms
- Revenue maximization focus vs simple rule-based approaches
- Comprehensive security analysis and hardening
- Professional repository structure with proper documentation
- Full test coverage and example configurations

Architecture:
- Modern Python project structure with pyproject.toml
- Secure gRPC integration with REST API fallback
- Modular design: API clients, policy engine, strategies
- SQLite database for experiment tracking
- Shell script automation for common tasks

Security:
- Method whitelisting for LND operations
- Runtime validation of all gRPC calls
- No fund movement capabilities - fee management only
- Comprehensive security audit completed
- Production-ready with enterprise standards
