Egglog Debugging Tools #141
Description
In writing a lot of egglog, I've realized the need for much, much better debugging tools and generally a much better interface for building egglog-related stuff in Luminal. #133 starts to address this, although we'll certainly have to build our own debugging apis on top. I am generally a fan of they way eggplant is moving, and once it reaches more of a point of stability (and hopefully the underlying egglog crate is synced back to egglog main) we can adopt it.
This generally ties into a broader debugger / visualizer push I want to do, but I'll leave that for another issue.
We should be able to have 2 different egglog expressions and easily get a plausable rewrite trajectory between them out.
