We didn't have a dedicated issue for this, so now there's one.

TODO:

[ ] Add a cfg for no-gil, but only allowed behind an experimental feature
Identify places that assume a Python<'_> indicates only a single thread is executing:
- [ ] pyo3::sync::GILOnceCell
- [ ] PyClassBorrowChecker

As a tiny piece of this and to try to learn the library better, I'm working on adding wrappers for the new GetItemRef C API functions in the 3.13 stable API. These are needed to be fully safe for free-threaded python and are nice to have anyway on older versions because strong references are easier to reason about.
