 Shared Workspace browser and picker plugin. `WorkspaceBrowser` fills the sidebar's `sidebar.workspaces` slot, while `WorkspacePicker` fills the page-local Session Intent hero's `conversation.hero.workspace` slot; both surfaces use the same Workspace menu and add flow.
 
-The browser renders grouped or flat Session rows from the global runtime hooks and owns Workspace add/rename/reorder plus in-Workspace Session reorder. A Workspace remembers whether it is closed or showing Sessions; an open Workspace shows five Sessions by default, offers a transient **Show more** control for the remainder, and returns to five after the whole Workspace is closed and reopened. View options combine grouping with Session order: **Manual** follows the Host Workspace account, while **Last updated** keeps a browser-local editable order and moves a Session to the front whenever a newer `updatedAt` arrives. Workspace drag order is Host-durable in either Session order mode.
+The browser renders grouped or flat Session rows from the global runtime hooks and owns Workspace add/rename/reorder plus in-Workspace Session reorder. A Workspace remembers whether it is closed or showing Sessions; an open Workspace shows five Sessions by default, offers a transient **Show more** control for the remainder, and returns to five after the whole Workspace is closed and reopened. View options combine grouping with one browser-persisted Session order: entering **Last updated** performs a complete recency sort and later user prompts or steers promote their Session once, while entering **Manual** preserves every current position and disables later promotion. Dragging edits the current order in either mode; Manual-mode drags also update the Host Workspace account. Workspace drag order is Host-durable in either Session order mode.
 
 Collapsed search is one header action beside the view and add actions. Activating it expands the field across the header; an outside click collapses only an empty query, while the clear control always resets and collapses it. A non-blank search query replaces either browsing mode with one flat result list: case-insensitive title and Workspace substring matches appear immediately, while a 250 ms debounced Host request adds ranked current-conversation content matches and snippets. The English search input and its defensive request path remove NUL, cap the query at the wire schema's 500 UTF-16 code units without splitting a surrogate pair, and preserve the existing debounce and cancellation behavior. Each new query aborts the preceding request; a failed content search leaves metadata matches visible with a warning. The list is capped at 20, asks the user to narrow broader queries, and opens the selected Session without clearing the query or jumping to a specific event.

-该浏览器通过全局运行时钩子将 Session 行渲染为分组或扁平形式，并负责 Workspace 添加／重命名／重排序以及 Workspace 内的 Session 重排序。每个 Workspace 会记住自身是关闭还是显示 Session；打开后默认显示五条 Session，其余条目通过临时的**展开其余**控件显示，而关闭并重新打开整个 Workspace 后会恢复为五条。视图选项把分组方式和 Session 顺序放在一起：**手动排序**遵循 Host Workspace 记账顺序，**最近更新**则维护可编辑的浏览器本地顺序，并在收到更大的 `updatedAt` 时把该 Session 移到首位。无论采用哪种 Session 顺序，Workspace 拖拽顺序都由 Host 持久化。

 折叠搜索是视图和添加操作旁的一枚区头按钮。激活后，输入框会扩展并占据区头；点击外部只会收起空查询，而清除控件总会重置并收起搜索。非空白查询会以单一扁平结果列表替代任一浏览模式：不区分大小写的标题和 Workspace 子串匹配项会立即显示，经 250 ms 防抖的 Host 请求则会加入经过排序的当前对话内容匹配项及其摘要片段。英文搜索输入框及其防御性请求路径会移除 NUL，将查询限制在传输 schema 规定的 500 个 UTF-16 代码单元内且不会拆分代理项对，并保留现有的防抖与取消行为。每次新查询都会中止前一个请求；内容搜索失败时，元数据匹配项仍会显示，同时给出警告。列表最多显示 20 条结果，并会在查询过宽时提示用户缩小范围；打开所选 Session 时既不会清除查询，也不会跳转至特定事件。
