Initial RUSTLE implementation with UCXL Browser and standardized codes

- Complete UCXL protocol implementation with DHT storage layer
- BZZZ Gateway for peer-to-peer networking and content distribution
- Temporal navigation engine with version control and timeline browsing
- Standardized UCXL error/response codes for Rust, Go, and Python
- React-based UI with multi-tab interface and professional styling
- libp2p integration for distributed hash table operations
- Self-healing network mechanisms and peer management
- Comprehensive IPC commands for Tauri desktop integration

Major Components:
- ucxl-core: Core UCXL protocol and DHT implementation
- BZZZ Gateway: Local subnet peer discovery and content replication
- Temporal Engine: Version control and state reconstruction
- Cross-language standards: Unified error handling across implementations
- Modern UI: Professional React interface with DHT and network monitoring

Standards Compliance:
- UCXL-ERROR-CODES.md and UCXL-RESPONSE-CODES.md v1.0
- Machine-readable error codes with structured payloads
- Client guidance for retry logic and error handling
- Cross-language compatibility with identical APIs
