fix(vagrant): ESC closes open panel before quitting to launcher

Previously ESC unconditionally switched to the launcher, leaving no way
to dismiss an open inspect-detail (or any panel-widget opened via
notify.post without a toggle key). Now ESC closes the active panel
first; only when no panel is open does it quit to the launcher.
