* fix(app): exit focus mode for sidebar shortcuts
Focus mode kept sidebar actions hidden after their handlers ran. Exit only after a sidebar action is handled so the requested action still takes effect.
* fix(app): order focus exit before sidebar action
Leave focus mode before dispatching the sidebar command so its handler runs against the visible panel state.
* fix(app): preserve focus mode outside workspaces
Only exit active workspace focus mode after a sidebar shortcut is handled. Keep persisted focus state unchanged when the shortcut has no foreground workspace target.
* fix(workspace): keep focus mode scoped and easy to exit
Route focus mode through the active workspace so persisted state cannot hide chrome on settings or other screens. Add a visible exit control and keep desktop window chrome aligned and visually quiet.
* fix(app): clarify muted chrome semantics
