feat: grounding before generation - retrieval is not a feature (#792)
SOUL.md compliance: 'When I have verified sources, I must consult them
before I generate from pattern alone. Retrieval is not a feature.
It is the primary mechanism by which I avoid lying.'

scripts/grounding.py:
  GroundingLayer with ground() - queries memory files + context before generation
  GroundingResult with grounded flag, confidence, sources, hedging indicator
  format_sources() for display
  Searches memory/*.md and provided context text

Tests: 6 passing
