Migrate Yarn to Bun

[coopbri]

I have been evaluating Bun in other projects, and it is starting to stabilize into a very convenient package. It can be used as a drop-in replacement for package management, runtime, testing (I still have frequent issues with this, however), automatic CJS/ESM resolution, and other DX benefits.

How is the exploration going so far ? we tried bun in early stages, was suuuper nice for simple projects, not mature enough for anything more advanced than just simple couple files :)
