Call WorkspaceController.refreshSelectedProjectTopology() from the existing
browser-resume refresh and the plugin-facing refreshAppData path, so worktrees
created or removed outside PI WEB become visible with no user action. No new
timer, watcher, process, or push channel; the resume path is already debounced
per animation frame and collapses concurrent requests.
Document the resume-scoped detection and the hiding of gone checkouts in the
FAQ, and add the changeset for the user-visible behavior.
