Master Dataset Seeding Script

This script populates Qdrant with:
1. SEC Forms (10-K) - Corporate compliance benchmark
2. Regulatory Data (GDPR, DPDP Act, LexGLUE) - Legal reference
3. Prepares Legal Case Data - Risk scorer training

Usage:
    cd backend && python scripts/seed_datasets.py

Or with options:
    python scripts/seed_datasets.py --sec-only
    python scripts/seed_datasets.py --regulatory-only
    python scripts/seed_datasets.py --prepare-ml-data
    python scripts/seed_datasets.py --all
