feat(desktop): 多智能体「团队」视图(运行·观测新增，轨迹仍默认)

把多智能体协调画成「协调者居中 + 专家工位环绕」，让最难读的一段——并行派发与综合
——变得一眼可读。执行轨迹保持默认视图；「团队」tab 只在多智能体运行时出现，
普通任务不塞多余 tab。

- lib/run.ts 加 isMultiAgent()(据 coordinator: 节点判定) + deriveTeam()：
  从现有执行事件流派生协调者/工位模型。与 deriveNodes 的区别是保留 start/end 时间戳，
  才能画并发时间轴；并解析专家收尾 detail("简报 X → Y")还原简报与产出。
- components/TeamView.tsx：径向布局(工位按角度均分环绕，>6 个降级为网格)、
  协调者实时思考流(接 token 流 + 闪烁光标)、并发时间轴(重叠一眼可见)。
  动效只标活跃态(派发链路流动/工位脉冲)——是状态编码不是装饰，带 prefers-reduced-motion 守卫。
  专家(kind=agent)与工具(kind=tool)图标区分。
- 零后端改动：数据全部来自现有 exec 事件(coordinator:/agent:/tool:)。

补 9 个单测覆盖派生逻辑(简报解析/失败态/时间窗/lead 不混入工位)。
实机经回放路径验证渲染(径向布局/简报/并发条/tab 条件出现)。
