clipmenud is declared as the operator's user unit, enabled and running, with a launcher that finds the display. Copy reads the clipboard back and fails with the reason. History and paste answer counts, times and lengths, never content.
Replaces the AUR greenclip (declared absent) with the official clipmenu, started
once from the session's xinitrc slot, its menu the launcher's dmenu command bound
as an i3 drop-in, its history in the runtime directory. Go tools read and change
clipmenu's own store under its lock.
