creatixchu 8cec74748b feat(host): adaptive directory-picker default via -auto chooser
Add @deepseek-ai/dsh-host-directory-picker-auto, a node-half-only chooser
that samples the host situation once at boot (bind host via a new
httpServer.host getter, SSH markers, platform, DISPLAY/WAYLAND_DISPLAY)
and mounts the matching dual-face backend (-native or -browse) as a real
Loader entry in the in-memory root tree; the effect disposer removes it.
Entry-level mounting keeps the seam's one-row-swaps-both-faces invariant:
the client module table discovers the mounted backend's browser half
exactly as a config row's. apps/cli now composes -auto as its
directory-picker row; composing a backend row directly remains the pin.

[English](README.md) | 中文
web GUI 宿主的**工作区目录选择 seam**:抽象服务 `DirectoryPicker``ctx.directoryPicker`),唯一契约方法 `capability()` 返回一个可辨识能力对象,描述操作者以何种方式选择目录。后端之间的差异在交互形态而不只是机制,因此 seam 显式建模形态而非统一方法集:`{ kind: 'native', pick(signal) }` 在宿主屏幕上打开一个原生 OS 选择器([`-native`](../directory-picker-native/README.md)`{ kind: 'browse', list(path?), createDirectory(path, name) }` 提供应用内浏览器驱动的列举/创建原语,可服务任何 OS 对话框都触及不到的远程客户端([`-browse`](../directory-picker-browse/README.md))。消费方按 `capability().kind` 分支;联合类型由可合并扩展的 `DirectoryPickerCapabilities` 映射派生(新后端在其中声明合并自己的形态),未知 kind 的文档化默认行为是隐藏选择入口而非失败。能力对象在服务生命周期内必须保持稳定。client 侧以镜像方式承接该 seam 而不经 wire 广播:每个后端包都是双面包,其 browser half 把匹配的选取交互注册进 ui-workspace 的目录流 slot——因此一行组合同时切换宿主能力与 client 流程。不应固定某种交互的组合改为挂载 [`-auto`](../directory-picker-auto/README.md) 选择器,它在启动时一次性判定宿主处境,并自行挂载匹配的后端行。
浏览原语以带类型的 `DirectoryPickerError` 失败(`directory-unreadable``directory-exists``directory-create-failed`,各自携带主体 `path`),消费网关将其 1:1 映射为协议错误码。`DirectoryEntry` 行携带宿主判定的 `hidden` 标志POSIX 点前缀约定),展示策略留在客户端;`DirectoryListing.crumbs` 是从文件系统根开始的祖先链,每个 crumb 都是跳转目标。设计依据、与 `ctx.fs` 的切分、策略裁决见[目录选择能力 seam Agent Note](../../../.agents/notes/implemented/architecture/2026-07-28-directory-picker-capability-seam.md)。
## 模型体验
无。该 seam 服务于 GUI 宿主的目录选择;这里没有任何内容进入模型请求。
#### KV 缓存影响
无;该包既不组装也不发送提供方请求。
## 已知限制与延期工作
- **没有多根词汇**——浏览契约每次列举只暴露一条祖先链;按部署限定可浏览根(以及 Windows 盘符之上的根枚举)等到出现需要它的消费方再做,见 seam Agent Note。
