jcfs 35915ff0cb refactor: Replace REST API with WebSocket-only architecture
- Remove all REST endpoints, replace with WebSocket message-based API
- Add WebSocket gateway with Hub and Client for connection management
- Add WebSocket handlers for Task, Agent, and Orchestrator services
- Add task subscription support for real-time ACP notifications
- Update all documentation to reflect WebSocket-first architecture
- Replace docs/openapi.yaml with docs/asyncapi.yaml
- Update e2e tests to use WebSocket via websocat

WebSocket endpoint: ws://localhost:8080/ws
Message format: {id, type, action, payload, timestamp}

Available actions:
- Board: board.list, board.create, board.get, board.update, board.delete
- Column: column.list, column.create, column.get
- Task: task.list, task.create, task.get, task.update, task.delete,
        task.move, task.state, task.subscribe, task.unsubscribe
- Agent: agent.list, agent.launch, agent.status, agent.logs, agent.stop,
         agent.prompt, agent.cancel, agent.session, agent.types
- Orchestrator: orchestrator.status, orchestrator.queue, orchestrator.trigger,
                orchestrator.start, orchestrator.stop, orchestrator.prompt,
                orchestrator.complete
