UI Slice 1b: Fenster-Menue auf ALLEN Fenstern (zentrale Shell-Injektion)

ShellUiHost injiziert das gemeinsame 'Fenster'-Menue beim Oeffnen zentral in jedes Fenster (nur wenn keins eigenes vorhanden ist, z.B. Launcher). Damit erscheint das Menue auf allen Core- und Modul-Fenstern ohne Achtfach-Designer-Duplikat, und jedes kuenftige Fenster bekommt es automatisch. Inhaltliche Controls bleiben designerbasiert; das Nav-Menue ist Shell-Chrome. Tests: +3 (WindowMenu.Populate: Inhalt Launcher/Views/Beenden, aktuelles Fenster fett+angehakt, offenes angehakt, Klick navigiert). 389 Tests gruen, --smoke-ui gruen.
