migrate_kg_overhaul

One-time migration for the knowledge graph overhaul.

Nondestructive – safe to run multiple times. Performs:

1. Creates vector + range indexes for new entity labels (Rule, Directive, Role).

2. Creates the pinned range index on ALL entity labels (including the 9 pre-existing ones).

3. Backfills pinned = false on every existing entity that lacks the property (WHERE e.pinned IS NULL).

python migrate_kg_overhaul.py [--redis-url redis://localhost:6379/0]

Reads $REDIS_URL by default.
