Validate JSON data files using Pydantic models.

This script validates all data files in kjvstudy_org/data/ using Pydantic models
for type safety and validation. Pydantic provides better error messages and
integrates naturally with FastAPI.

Usage:
    python scripts/validate_data.py              # Validate all files
    python scripts/validate_data.py --file bible_metadata.json  # Validate specific file
    python scripts/validate_data.py --verbose    # Show detailed output
    python scripts/validate_data.py --generate-schemas  # Generate JSON schemas

Requirements:
    pip install pydantic (already installed with FastAPI)
