creatixchu 85ca8be104 feat(host,client): compose directory picking through slots — dual-face -native, no wire advertisement
ui-workspace's two trigger surfaces each declare a single-kind directory-flow
hole (conversation.hero.workspace.directoryFlow / sidebar.workspaces.directoryFlow,
same owner contract) and keep only the trigger and the adoption: the Open-local-
folder entry renders while the surface's hole is occupied, and the occupant
reports one picked path per open through the hole's owner conversation
(open/busy/onPicked/onCancel/onError).

directory-picker-native becomes dual-face: its browser half fills both holes
with a renderless occupant driving host.pickDirectory, so the cordis.yml row
that mounts the backend also composes the client interaction — a mismatch is
impossible and a second flow package fails at client load.

With composition wiring both sides, the host.describe.directoryPicker
advertisement and the client's kind branching lose their last consumer:
the field, WorkspacesService.directoryPickerKind(), the DirectoryPickerKind
wire type, and the picker's per-open describe read are deleted. The connection
fixture now serves a deterministic pickDirectory path so the keyless snapshot
drives the full pick-then-adopt flow. ui-workspace's hand-rolled declaration
deferral is replaced by the deferRegistration helper it duplicated.

共享 Workspace 选择器插件。`WorkspaceBrowser` 注册到侧边栏的 `sidebar.workspaces` slot`WorkspacePicker` 注册到页面局部 Session Intent 主视觉区的 `conversation.hero.workspace` slot,因此两个表层使用同一菜单和创建流程。
该选择器通过全局 `useWorkspaces` hook 列出真实的 Host Workspace 实体。选择 Workspace 会调用 slot owner 的 `onPick` 回调,重新定位前端 Session 对象。每个注册各自声明一个**目录流子洞**(`single` kind`conversation.hero.workspace.directoryFlow``sidebar.workspaces.directoryFlow`),由组合的选择器包 client half 填入其选取交互——今天是 [`-native`](../../host/directory-picker-native/README.md) 后端的无渲染 OS 选择器驱动,`-browse` 组合下则是应用内浏览对话框。平铺显示的 **打开本地文件夹…** 操作仅在本表层的洞被占用时渲染(每次菜单渲染读取占用状态;洞为空意味着该组合没有选目录能力——seam 文档化的无流程默认行为)。本包持有触发与接纳:占用者经洞的 owner 会话(`open`/`busy`/`onPicked`/`onCancel`/`onError`)每次打开上报一个所选路径,owner 通过对象层接纳它,并等待 Workspace 列表投影刷新后才选中已提交的 Workspace;取消操作不会显示提示,错误落入可重试的文件夹对话框,其 **重新选择** 会重新打开流程。**创建新工作区** 操作保留名称对话框,并禁用列表中已有的名称,而 Host 对并发或非 UI 调用方仍具有最终决定权。运行时 Session 与 Workspace 服务负责物化。Workspace 行内的 Delete 操作会打开确认框,说明保留边界、阻止重复提交,并在失败时保持打开;成功后,该分组会被移除,其 Session 则留在 Ungrouped 下。
两个目标 slot 都由其他插件声明,因此 `apply` 通过声明感知的延迟机制完成注册,并在声明该 slot 的插件恢复后重新注册。
## 模型体验
无。选择器属于浏览器 chrome;这里没有任何内容进入模型请求。
#### KV Cache 影响
无;该包既不组装也不发送提供方请求。
## 已知限制与暂缓事项
- **没有 Session 删除控件**:现有 Session 菜单行仍仅提供视觉效果;删除 Workspace 注册记录不会删除 Session。
- **原生文件夹选择依赖本地 Host 载体**:在 `-native` 组合下,仅使用 fixture(测试前置数据)的部署或远程浏览器部署无法打开本地操作系统对话框;模态框会显示平台故障,并允许重试。可远程的选取是 `-browse` 组合的应用内流程。
