Show a failure state when a presented command exits non-zero

The floating-terminal presentation wrapper showed the green "Done!"
prompt for every exit code except Ctrl-C, so a failed update or channel
switch closed looking like a success. Pass the command's exit code
through to omarchy-show-done and render a red "Failed (exit code N)!"
prompt when it is non-zero. The pkg install/remove pickers get the same
treatment.
