Bump requires-python to <3.15, CasADi to 3.7.2, and JAX to >=0.7.0,<0.9.0 for Python 3.14 compatibility. Add a PEP 508 platform marker to exclude JAX on macOS x86_64 since JAX dropped Intel Mac wheels in 0.5.0. Remove explicit casadi pin since it is managed transitively through pybammsolvers.Update idaklu_jax.py for JAX 0.7+ API changes (explicit np.int64 casts, type check adjustments). Add raise_jax_not_found() helper with a platform-aware error message so macOS Intel users get a clear explanation.

Add python_version >= '3.11' to the JAX dependency marker since JAX 0.7+ requires Python 3.11. Update test_bruggeman_invalid_values_raise regex to match both the old 'math domain error' and the new Python 3.14 message 'expected a positive input' (cpython#101410).
Update all workflows, documentation, Dockerfile, ReadTheDocs config, and pyproject.toml classifiers to include Python 3.14. Drop Python 3.10 from CI test matrices.
