- Translate the zh Agent Note's title and section headings and align
its rail terminology with the established zh READMEs (轨道).
- Disambiguate 'the browser's listener' to WorkspaceBrowser's in the
English note.
- Record the in-flight outside-click exception in the ui-workspace
README (both languages) and the owning workspace-sidebar feature
note, cross-linked to the bug-fix note.
- Add an apps/web real-browser scenario pinning the document-level
bubble the jsdom test cannot replay: one real rail click must leave
the search expanded and focused, and a genuine outside click must
dismiss it afterwards. Negative-controlled against the unguarded
code (fails in 12s on the aria-expanded assertion).
- Register the new e2e file in the host tsconfig face and the client
face's exclude list.
