fix(reliability): cross-session-affective

- Fix state key mismatch: soul.el layered_cycle now reads conv_history
  (not conversation_history), unblocking the safety_score_distress_history
  history-amplification path in safety_threat_score
- Add safety_augment_system call on the main handle_chat path so the
  phrase-list bell detector fires on all chat turns, not just dharma rooms
- Add cross-session affective engram query in load_identity_context() at
  boot; stores distress/crisis signals from prior sessions under
  soul_affective_context with a 7-day soft recency filter
