feat: add distributed async dataset with unix socket server and refactor agent communication bus

Implement AsyncDataSet class supporting client-server model over Unix sockets with SQLite backend, including KV store, table management, and concurrent query handling. Rename `get_messages` to `receive_messages` in AgentCommunicationBus and update all callers. Remove deprecated `get_recommended_agent` function from agent_roles, `invalidate_tool` from tool_cache, and legacy `receive_messages` wrapper. Add multiplexer command routing in handlers with `/prompt` command support. Introduce comprehensive help documentation system for workflows. Update default API URLs to production endpoints and refactor adaptive context window calculation in AdvancedContextManager.
