Compile with STABLE_ABI for Python 3.13 and later

[hpkfft]

How does specifying the following for scikit-build-core in pyproject.toml:

[tool.scikit-build]
wheel.py-api = "cp313"

interact with specifying STABLE_ABI to nanobind_add_module()?
I think the latter sets Py_LIMITED_API=0x030C0000.

How best to define Py_LIMITED_API=0x030D0000 and build using the stable ABI when the extension is intended only to support Python 3.13 and later?

I don't actually want to do this for any extensions I have written; I just thought I'd share this scenario for future consideration.

nanobind doesn't have any benefits building for Python 3.13 or later. So if your goal is to make stable ABI builds, I would set this to 3.12.
