loregrep 0.6.0

#!/usr/bin/env python3
"""
Real test script for Python bindings after the API fixes.
This validates the key functionality we implemented with actual tests.

Prerequisites:
- Install with: maturin develop --features python
- Or build wheel with: maturin build --features python --release

This script performs actual tests on the Python bindings to ensure:
- Import works correctly
- API consistency is maintained
- Field names are correct
- Error handling works
- Async operations function properly
