## Summary

The previous fix aviator-co#575  attempted to fix the squash command, but actually was incorrect and I believe the original command was working as expected all along. I suspect the issue I was seeing was actually down to my repo being in a bad state - _still investigating the cause there_


## Test Coverage Added
To try and prevent this happening again I have added a bunch of tests (with the help from opencode), to try ensure that the behaviour remains as expected
