[Code scan] Align Python 3.12 support with pinned h5py wheels #46

This issue comes from a Codex global repository scan.

Problem

The project declares Python 3.12 support:

But h5py is pinned below 3.11 and excludes 3.10:

On a Python 3.12 environment, uv sync selected h5py==3.9.0 and attempted a source build, which failed without system HDF5/pkg-config. This makes the advertised Python 3.12 installation path fragile, especially for users following the README or install.sh with their current Python.

The install script uses the current Python interpreter:

Suggested fix

Either restrict requires-python to versions with available pinned binary wheels, or loosen/adjust the h5py constraint so Python 3.12 can install from wheels. The install docs/script should also make the expected Python version explicit.
