refactor: 移除 Team 和 Swarm 协作功能

功能论证结论：Team（团队）和 Swarm（协作）为零后端支持的
纯前端 localStorage 空壳，Pipeline 系统已完全覆盖其全部能力。

删除 16 个文件，约 7,950 行代码：
- 5 个组件：TeamCollaborationView, TeamOrchestrator, TeamList, DevQALoop, SwarmDashboard
- 1 个 Store：teamStore.ts
- 3 个 Client/库：team-client.ts, useTeamEvents.ts, agent-swarm.ts
- 1 个类型文件：team.ts
- 4 个测试文件
- 1 个文档（归档 swarm-coordination.md）

修改 4 个文件：
- Sidebar.tsx：移除"团队"和"协作"导航项
- App.tsx：移除 team/swarm 视图路由
- types/index.ts：移除 team 类型导出
- chatStore.ts：移除 dispatchSwarmTask 方法

更新 CHANGELOG.md 和功能文档 README.md
