feat: add smart-opposite resize option

[wesbos]

Fixes #741

I've never worked on a swift app, but it seems like a small add so hopefully this is OK.

Please ping me back when you fix the CI

You also need to update this line https://github.com/nikitabobko/AeroSpace/pull/742/files#diff-7a3999a307e560d8f439d95603d6b511bfaefe93607e2e0494505be04af95c0cR12

Thanks, merged with the following patch:

otherwise the code crashes.

Please next time always run your code before submitting it, even if it looks trivial
