Return a non-zero exit code when a command fails because of an issue with the scripting addition

Return a non-zero exit code if a command fails because the scripting addition is not installed or failed to get addresses.

This would be nice for scripts so chaining with && or set -e fails early. Currently there's no error message printed to stderr and the exit code is 0, indicating success.

Do you think it is useful as an end-user to be able to tell the difference between the various ways the scripting-addition fails, or is a generic catch-all "the operation could not complete due to an error with the scripting addition" good enough (with a non-zero exit code of course).

If I recall correctly I wanted to write this in some place:

yabai -m space --focus 1 || skhd --key "ctrl - 1"

So just failing with a generic code is enough.
