Implement UCXL Protocol Foundation (Phase 1)

- Add complete UCXL address parser with BNF grammar validation
- Implement temporal navigation system with bounds checking
- Create UCXI HTTP server with REST-like operations
- Add comprehensive test suite with 87 passing tests
- Integrate with existing BZZZ architecture (opt-in via config)
- Support semantic addressing with wildcards and version control

Core Features:
- UCXL address format: ucxl://agent:role@project:task/temporal/path
- Temporal segments: *^, ~~N, ^^N, *~, *~N with navigation logic
- UCXI endpoints: GET/PUT/POST/DELETE/ANNOUNCE operations
- Production-ready with error handling and graceful shutdown
