This enables GUI clients to identify which agent emitted each message, solving the issue of interleaved messages when multiple sub-agents run in parallel. Changes: - Add optional session_id field to BaseMessage (backward compatible) - Add set_session_context/get_session_context to MessageBus - Auto-tag messages with current session_id in emit() - Set/restore session context in invoke_agent tool When an agent invokes a sub-agent, the session_id is set as the current context. All messages emitted during that sub-agent's execution are automatically tagged. The previous context is restored when the sub-agent completes.
