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）
