Follow-up to #34 (review 4789146976).

- Actions menu samples the selection's running state once, when it opens
  (`openActions`), instead of reading `RunningAppsMonitor` live: an app
  launching or quitting elsewhere no longer adds or drops the Quit row
  while the menu is up. All eight open sites now funnel through the one
  method.
- `RootPaletteView` no longer observes `RunningAppsMonitor`, so a
  workspace launch/terminate stops re-rendering the whole palette; only
  `LauncherList` observes it, for the running dot.
- `RunningAppsMonitor.refresh` republishes only on a real change.
- ⌘↵ mirrors the menu row's condition (`kind == .application`) so it
  can't swallow a press it won't act on.
- Quit All confirms via `NSAlert` before terminating, resolving the
  target list once so the set confirmed is the set that quits. ↵ is
  bound to Cancel, not the destructive button.
- Quitting an app restores focus unless the app quit was `previousApp`.
- `xmark.app` -> `xmark.circle`; drop the now-unused `AppLauncher.quitAll`.
