feat(python-version): support Python 3.9-3.14, first-class 3.12/3.13#382
Conversation
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. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
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).

…g 3.13 install) ultranest==3.6.2 was already removed as an actual library dep some time ago — no autogalaxy/autolens code imports it. The dangling pin in the [optional] extra was breaking 3.13 install because ultranest 3.6.2's Cython source uses np.int_t (removed in newer numpy), so wheel build fails. Cut from PyAutoGalaxy and PyAutoLens optional extras. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Summary
Part of the Python version policy change supporting Python 3.9–3.14 across PyAuto. First-class support remains 3.12/3.13.
