🐍 Add Python 3.13 support and update CI configuration

Adds Python 3.13 to the test matrix and updates the PyPI release job
to use the latest Python version. Removes legacy Python 3.9 workaround
since it's no longer in the test matrix. Keeps project current with
latest Python releases for better compatibility and performance.
