Parity test: verify RECON domain taxonomy matches PeerTube categories.

Tests:
1. DOMAIN_CATEGORY_MAP keys match VALID_DOMAINS exactly
2. PeerTube API returns all 18 RECON categories (IDs 100-117) with correct labels

Usage:
    cd /opt/recon && source venv/bin/activate
    python3 tests/test_constants_parity.py
