fix: resolve Python 3.8/3.9 compatibility issues

- Fix incorrect os.sys.version_info to sys.version_info
- Add missing sys import
- Update setup.py version to match __version__
- Fix author name consistency (Fahad Gilani)
- Add typing-extensions for Python <3.10 compatibility
- Apply black formatting to fix whitespace issues
- Add debug workflow to help diagnose CI failures

This should resolve the failing tests on Python 3.8 and 3.9.
