Closes #295.

Set the wheel’s minimum Python version to 3.11, update the classifiers and release notes, and move the former 3.10 CI jobs to supported interpreters.

All 24 test jobs remain in the matrix. The two jobs that exercise distro-provided SciPy with ATLAS and OpenBLAS move to Ubuntu 24.04 and use its system Python 3.12. The installer uses /usr/bin/python3 so those jobs load the distro’s SciPy. The OpenBLAS job uses Noble’s libopenblas0-pthread package.

Validation

• Built and installed the wheel on Python 3.11. The wheel declares Requires-Python: >=3.11, and pip rejects it when resolving for Python 3.10.
• All nine pre-commit hooks passed. The workflow parses with 24 jobs, and the installer passes bash -n.
• The Linux Python 3.11 suite recorded 72 passed and 36 skipped. One concurrency stress test timed out during the full run and passed in isolated runs on both this branch and the upstream base.

GitHub CI

The migrated Ubuntu 24.04 ATLAS and OpenBLAS jobs passed in the PR run. Six Clang 18 jobs failed during LLVM dependency installation before the tests ran. The same six jobs fail in the scheduled upstream run, including the Python 3.10 version of the Linux conda job. The installer reports a missing apt-key command and HTTP 404 responses from its apt repository.

Codex assisted with the implementation and local validation.
