feat(python-version): support Python 3.9-3.14, first-class 3.12/3.13 (#293)

* feat(python-version): support Python 3.9-3.14, first-class 3.12/3.13

Wide-support / narrow-first-class model for Python versions across the
PyAuto family. Python 3.12 and 3.13 remain the recommended versions.
3.9, 3.10, 3.11, 3.14 install cleanly but emit a loud bypassable
warning at import time. JAX moved to optional [jax] extra gated on
python_version >= '3.11' (so 3.9/3.10 users get numpy-only mode
without install failures).

Coordinated change across PyAutoConf, PyAutoArray, PyAutoFit,
PyAutoGalaxy, PyAutoLens, PyAutoBuild, and the 6 workspace repos. See
sibling PRs on the feature/python-version-policy branch in each repo.

* ci: narrow per-PR matrix to 3.12/3.13; install [optional] uniformly

Per-PR CI now tests only the first-class Python versions (3.12, 3.13).
Wide-span 3.9-3.14 verification moves to PyAutoBuild's python_matrix.yml
workflow (weekly + on-demand).

Install commands now always use the [optional] extra so JAX is
available on both 3.12 and 3.13 (the conftest.py eager `import jax`
was failing on 3.13 because the previous CI only added [optional] for
3.12).
