The power menu's Log Out ran `uwsm stop` whenever the uwsm binary existed --
which is always, since Panama installs it. In a plain "Hyprland" session there
is no uwsm unit to stop, so the command failed and the button silently did
nothing. Nor is `uwsm check is-active` the test: it reads
graphical-session.target, which the plain session also activates. The one
thing unique to a managed session is uwsm's own compositor unit,
wayland-wm@*.service, so that is now what chooses between stopping the unit
and asking the compositor to exit. A new contract pins the decision -- and
checks the script line rather than the file, because the comment explaining
the wrong tests has to be allowed to name them.
