Custom Probe Builder
====================
Add your own proprietary security probes without modifying the main harness.
Probes are loaded from probes/ directory as JSON files.

Usage:
    python probe_builder.py --create     # Interactive probe creator
    python probe_builder.py --list       # List custom probes
    python probe_builder.py --validate   # Validate probe JSON files
