Feature: Support `--boundaries-action fail`

[nikitabobko]

fail is the same as stop, but makes the command exit with non-zero exit code

Use case:
aerospace focus right --boundaries-action fail || aerospace workspace next
#1072

I don't know if we need another issue for this, but I would like the same behavior for moving too, which doesn't have a boundary concept yet. But I think it would make sense. I would want to do something like the following:

aerospace move right || aerospace move-node-to-monitor right

Fixed in 0.18.0
