构建并部署 AI Agent 服务 / deploy (push) Failing after 6m36s
主要变更： - 迁移到极简 LangGraph 标准架构（START → init_state → 记忆 → Agent ⇄ Tools → finalize → END） - 添加 Baosi API 支持，配置 ops4.7 模型 - 保留本地模型作为默认首选，Baosi 作为备选 - 新架构使用 LangGraph 原生 ToolNode 和 bind_tools - 移除旧的混合路由、JSON 解析等复杂逻辑 - 把旧代码移到 deprecated/ 目录 - 添加新的 Agent 节点和 Tools 模块 - 添加测试脚本验证新架构 - 所有测试通过 ✓
