Drops Python 3.12 and adds 3.15 per SPEC 0, testing stable on 3.13 and 3.15 and pre-releases on 3.15.
The 3.15 jobs will fail until h5py and pyarrow publish cp315 wheels.

Python 3.12 reaches its SPEC 0 drop date in October 2026, so requires-python is now >=3.13.
Stable tests run on 3.13 and 3.15, pre-release tests on 3.15.
The 3.15 jobs cannot pass yet: h5py (required by anndata), pyarrow and scikit-misc publish no cp315 wheels, and building them from sdist needs system HDF5, Arrow C++ and a Fortran toolchain.
