Code Review

This pull request adds support for Python 3.14 by updating the test configurations in noxfile.py and the package classifiers in setup.py. The changes are correct and follow the established pattern for adding new Python versions. I have one suggestion to also update the prerelease_deps nox session to use Python 3.14 to ensure testing against the latest version.
