Thanks a lot for the update, this is really helpful!

I left some comments, most of them minor.
Main points are:

• We can move flash attention installation to uv, creating a new dependency group.
• I'm not confident hatchling will work with the current publish pipeline. You can probably test this by creating a new workflow that
  • is triggered on pull_request
  • builds the package but doesn't publish it (we can remove this workflow before merging).
