Test script for hybrid indexing system.

This demonstrates the new tree-sitter based indexing without requiring
full dependency installation.

To run the full test:
1. Fix venv or create new one:
   python3 -m venv venv_new
   source venv_new/bin/activate
   pip install -r requirements.txt

2. Run this script:
   python3 test_hybrid_indexing.py /path/to/pistn/project
