"""CLI wrapper for theme enrichment pipeline.

Runs the consolidated theme enrichment pipeline with command-line options.
For backward compatibility, individual scripts can still be run separately,
but this provides a faster single-pass alternative.

Usage:
    python code/scripts/enrich_themes.py --write
    python code/scripts/enrich_themes.py --dry-run --enforce-min
