构建并部署 AI Agent 服务 / deploy (push) Successful in 5m41s
主要变更： - 简化 agent_service：移除复杂双协程，只用 stream_mode=["updates"] - stream_context：提供更清晰的 API (set_stream_queue/get_stream_queue) - main_graph_builder：简化图结构，移除 tools 节点和条件边 - agent 节点：包含完整 ReAct 循环 + 流式 Tool Calling 拼接 - 前端：适配新的事件格式 - 添加测试文件：test_full_react_streaming.py, test_stream.py
