feat(agent): 抽屉与会话页统一成一个对话界面,子会话在父会话里实时可见

- 抽屉和会话页渲染同一套 GoalComposer / AgentRunPanel;抽屉标题即最近会话切换,
  头部只有新对话、在页面打开、关闭;去掉右下角悬浮按钮和最小化小窗
- 会话列表合一:对话与巡检混排带类型小标签,搜索 + 一个状态下拉,只列顶层会话
  (GET /agent/runs?roots=true,新增可选参数)
- 子会话卡片:由镜像的 subagent_* 事件折成,显示任务、状态、当前步骤、用时、调用次数、费用,
  可展开看过程、可打开;顶部「N 个子会话运行中」跳到卡片;subagent_completed 加可选 durationMs
- 回答去内部字段:汇报规则禁止照抄键值与字段表;展示层 stripInternalFields 把字段行 / 字段表移进技术信息
- 开场建议按页面给 2 条完整问法、点了直接发;指令只留 /先给方案,/重跑 改成「重新运行」按钮
