NomenAK 3e40322d0a refactor: Complete V4 Beta framework restructuring
Major reorganization of SuperClaude V4 Beta directories:
- Moved SuperClaude-Lite content to Framework-Hooks/
- Renamed SuperClaude/ directories to Framework/ for clarity
- Created separate Framework-Lite/ for lightweight variant
- Consolidated hooks system under Framework-Hooks/

This restructuring aligns with the V4 Beta architecture:
- Framework/: Full framework with all features
- Framework-Lite/: Lightweight variant
- Framework-Hooks/: Hooks system implementation

Part of SuperClaude V4 Beta development roadmap.
