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 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
