Code Review

This pull request effectively adds support for Python 3.14 by updating configuration files, dependencies, and tests. The changes are mostly correct, but I've identified a few areas for improvement. These include a potential copy-paste error in a build configuration file, inconsistencies in file formatting, a typo in a test function name, and a discrepancy in the supported Python versions listed across different files. Please review my specific comments for details.
