remove_toolbar()/remove_menu() nahmen Toolbar und Menü bisher nur aus der sichtbaren Leiste, das Qt-Objekt blieb als Kind von main_window bestehen. Beim Neuladen mit dem Plugin Reloader meldete QGIS deshalb "removing duplicated widget(s) not cleaned up by the plugin during unload: LnoSachsenToolbar" - der defensive Workaround in init_ui() (Suche nach übrig gebliebenen Toolbars) kaschierte das nur beim nächsten Laden, nicht beim Unload selbst. remove_all() ruft jetzt deleteLater() auf beide Objekte, bevor die Referenzen verworfen werden - dieselbe Behandlung, die init_ui() schon für Altlasten nutzt. deleteLater() ist in PyQt5 und PyQt6 identisch, keine QGIS3/4-Fallunterscheidung nötig.
