fix: Improve compatibility with Alpine Linux

Alpine's ps doesn't support the -x command. SO suggests -ef is more than sufficient as a replacement.

Is there anything I can do to help this along?

Hey, I'm sorry for the delay. My wife and I just had a baby a few weeks ago, and I've taken the last few months off to focus on helping her and now our baby. But, this looks good. I'll merge and release when I get back to my laptop in November

Congrats!
