Subject: [PATCH] fix(resonance): remediate 0.85 score flatlining (P1-4)

- Raised ContentMemoryDB cache threshold from 0.95 to 0.98 to prevent cross-post poisoning.
- Implemented continuous resonance scoring by storing and retrieving 'resonance_score'
  in ContentMemoryDB.
- ResonanceEngine now prioritizes high-fidelity raw scores from cache over
  discrete 'high/medium/low' mapping.

TDD: 3 tests verifying threshold and scoring logic integrity.
