Title: Production Audit Implementation: Comprehensive Codebase Analysis and Security Fixes (#15)

Key features implemented:
- Added new checkpoint file agtune-lyrics-checkpoint.json containing serialized model weights and parameters for the AG-TUNE poetry generation system.
- Implemented comprehensive security and performance fixes across the React DOM reconciler based on senior staff engineering audit standards.
- Added new core algorithmic components for kernel PCA, TD learning, Rete matching, and CYK parsing in the AG-TUNE system.
- Implemented full UI components with training controls, generation settings, and real-time visualization of internal states.

Overall improvements include fixing critical vulnerabilities like prototype pollution and unsafe string operations, implementing robust error boundaries, adding proper type safety, and enhancing observability through logging and metrics. The AG-TUNE system now includes full serialization support, improved numerical stability, and a production-ready UI with real-time feedback.
