Andreas Kling b91ff9ebfd UI/Qt: Keep macOS app alive without windows 
Disable Qt quit-on-last-window behavior on macOS and install an
application-level menu so useful commands remain available after the
last browser window closes.

Reuse shared application actions and menus for Settings, Bookmarks,
History, Help, and global appearance controls. Centralize window-aware
commands such as New Tab, New Window, Open File, Open Location, and
Reopen Recently Closed so the browser window and windowless app menu
use the same behavior. Keep the location editor focused for new blank
windows after the native window has been activated.
