feat: rwfx 任务深链支持目的树闸门 + 任务↔对话(1:N)绑定

后端
- config.yaml 新增 task_deeplink 段：完整 URL（无 base）+ test/delete_test 两个独立测试开关
  + mock 假数据（目的树 / delete 结果，可随时编辑）
- 新增 TaskDeeplinkConfig 模型挂到 AppConfig；新增公开只读接口
  GET /api/public/config/task-deeplink 暴露给前端（/api/public 已在鉴权白名单）

前端
- 登录深链 goPath=rwfx 进入「任务工作区」：左侧按 metadata.taskId 过滤的对话列表
  （新建对话 / 编辑 / 下一步 / 清除任务记录）+ 右侧问答
- 新建对话（含首次进入）顶部展示目的树闸门：有数据弹覆盖确认→调 delete，success 才开始问答；
  恢复历史对话不跑闸门
- 新建 thread 打 metadata.taskId 标签实现「一个任务挂多个对话」(1:N)
- 地址/开关/假数据全部走后端配置，拿不到时用内置默认值兜底；test/delete_test=true 走假数据
