Version: 0.9.47.dev.260427

后端：
1. execute 节点继续拆职责——超大 execute.go 下沉为 node/execute 子包，按决策流、动作路由、上下文锚点、工具执行、状态快照、工具展示与参数解析拆分；顶层 execute.go 收敛为桥接导出，降低单文件编排/业务/模型/工具逻辑混写
2. 节点公共能力继续沉到 shared——抽出 LLM 纠错回灌、完整上下文调试日志、thinking 开关、统一上下文压缩、可见 assistant 文本持久化等 node_* 公共件，减少 execute 独占实现并为其他节点复用铺路
3. speak 文本整理能力独立收口——新增 speak_text 辅助文件，补齐正文归一化的独立承载，继续收缩 execute 主文件体积

前端：
4. NewAgent 时间线接入 business_card 业务卡片协议——schedule_agent.ts 新增 task_query / task_record 卡片载荷类型与 business_card kind；AssistantPanel 增加业务卡片事件存储、时间线恢复、块渲染分支与 BusinessCardRenderer 接入，同时保留 interrupt / status / tool / reasoning 多块并存
5. 新增任务查询卡片与任务记录卡片组件，并补充 DesignDemo 设计预览页与路由，前端可先行验证 business_card 的视觉与交互落点

文档：
6. 新增 newagent business card 前后端对接说明，明确 timeline kind、payload 结构、卡片分类、前后端发射/渲染约束
