aitbc 03d409f89d feat: implement agent coordination foundation (Week 1)
 Multi-Agent Communication Framework
- Implemented comprehensive communication protocols
- Created hierarchical, P2P, and broadcast protocols
- Added message types and routing system
- Implemented agent discovery and registration
- Created load balancer for task distribution
- Built FastAPI application with full API

 Core Components Implemented
- CommunicationManager: Protocol management
- MessageRouter: Advanced message routing
- AgentRegistry: Agent discovery and management
- LoadBalancer: Intelligent task distribution
- TaskDistributor: Priority-based task handling
- WebSocketHandler: Real-time communication

 API Endpoints
- /health: Health check endpoint
- /agents/register: Agent registration
- /agents/discover: Agent discovery
- /tasks/submit: Task submission
- /messages/send: Message sending
- /load-balancer/stats: Load balancing statistics
- /registry/stats: Registry statistics

 Production Ready
- SystemD service configuration
- Docker containerization
- Comprehensive test suite
- Configuration management
- Error handling and logging
- Performance monitoring

🚀 Week 1 complete: Agent coordination foundation implemented!
