Fix wrapper scripts to use correct library version

- Removed debug output from wrapper scripts
- Added developer notes about using 'python' for local development
- Confirmed --overwrite flag works correctly when calling library

The issue was that 'uv run --script' uses cached PyPI versions
instead of local editable installs. For development, run with
'python tools/04_generate_parquet.py' to use local library changes.
