Feature idea: flag to remove all code that is unused when running a single test

[Anton-4]

I'm delighted this project exists, thanks for making it ❤️
Debugging is hard in large projects, so I've always wanted a tool that could remove all code that is unused when running a single test. Being able to diff the minimized code for a single test between two commits could also make debugging a lot easier.
I believe being able to minimize the code would also make it a lot easier and cheaper for an LLM to find the cause of the bug.
