feat(task-deeplink): 会商/智能体问答嵌入任务管理布局

任务深链（goPath=3qfx/3qfx-A 等）跳转的多智能体会商 / 单智能体问答
改为嵌进「任务管理」对应业务上下文，侧边栏保持 COH中任务→对应业务 高亮。

- StrategyRoutes: task-management 配下新增 6 条嵌入路由（每业务 roundtable + agent）
- AgentChatPage: 新增 chatBasePath 可选属性，覆盖发消息后 URL 改写 / 新会话路径
- task-deeplink: 跳转目标改为业务别 task-management 嵌入路由（BUSINESS_TASK_BASE）

 - **UI**: Radix UI primitives + TailwindCSS v4 + shadcn-style components in `src/components/ui/`

After login it calls the consumer API `GET {VITE_AIPI_CONSUMER_URL}/taskAnalysSearch/cop-task-detail?taskId=` (header `Authorization: Bearer admin`, auto-injected by `utils/request.ts`), stashes the full `data` (`id/overview/taskDirection/taskName/taskContent`) into `sessionStorage["login.copTaskDetail"]`, then routes by `goPath`: base codes `3qfx`/`rwfx`/`xdfx` → that business's configured **single agent** Q&A (resolved via `/api/business-mapping`, opening message in `sessionStorage.pendingAgentMessage`); the `-A` suffix (`3qfx-A`/…) → **multi-agent roundtable** with `roundtablePrefill.businessCode` so the page auto-selects the configured 业务链条. goPath→businessCode: `3qfx`→`3Q`, `rwfx`→`6BF`, `xdfx`→`7BF`.

The agent chat is rendered via `TaskEmbeddedAgentChat`, which passes `AgentChatPage`'s `chatBasePath` prop so the post-send URL rewrite + new-chat button stay in the task-management context (instead of the standalone `/agents/...` route).
