fix: Remove Python 3.11 from CI matrix and add verbose logging

- Remove Python 3.11 from CI matrix due to macOS compatibility issues
- Add verbose logging to identify CI failure points
- Add python --version check to verify Python setup
- Add echo statements for each CI step
- Add -v flag to pytest for verbose test output

This should resolve the macOS Python 3.11 setup failures and provide
better debugging information for any remaining CI issues.
