chore: support 3.14t

[phi-friday]

Adds Python 3.14t support and updates compatibility checks for the free-threaded build.

Summary by CodeRabbit

• Compatibility

  • Added a Python “Free Threading” classifier for Python 3.14 free-threaded builds.
  • Refined dependency requirements with more precise Python-version markers and updated minimum versions for newer Python.

• Tests

  • Made notebook execution order deterministic for more consistent test runs.

• Maintenance

  • Updated the automated test workflow matrix to cover additional Python and NumPy/SciPy constraint combinations, including conditional dependency installation logic.

📝 Walkthrough

Walkthrough

The package declares free-threading support, refines dependencies for newer Python versions, adds Python 3.14t CI coverage with NumPy/SciPy constraints, and sorts notebook test execution.

Changes

Python compatibility updates

Layer / File(s)	Summary
Runtime metadata and dependency markers pyproject.toml	Adds the Python free-threading classifier and partitions dependency requirements for Python 3.13+ and 3.14+.
CI interpreter matrix .github/workflows/run_tests.yml	Adds Python 3.14t coverage, separates NumPy major versions, excludes incompatible combinations, and installs matching NumPy/SciPy constraints.
Deterministic notebook execution tests/test_notebooks_run.py	Sorts discovered notebooks before parametrized execution.

Consider upgrading actions/checkout to v4.

actions/checkout@v3 is deprecated and uses Node 16 which is no longer supported by GitHub Actions. Upgrading to actions/checkout@v4 is a low-risk change that avoids future runner deprecation warnings.
