 Prevents long-term memory degradation and enables compression.

-- [ ] Consolidation pass — merge related low-weight episodes into summary nodes

+- [x] Dry-run candidates endpoint — `GET /sessions/:id/consolidation-candidates` with age + session-size floors (observe-only phase before destructive pass)
