feat: break the reflection loop — narrative is slow-consolidated, not rewritten each cycle

The remaining feedback loop: reflect() dumped her full self-state (incl.
self_narrative) into the prompt and asked her to "update" it -> paraphrase -> save
-> feed back -> calcify. That (not the model) is what generated the recurring
"supportive presence balancing emotional intelligence for Brian" drift — even
Dolphin echoed it when handed the saved narrative.

Fix (her inner life now runs on one cognition model):
- reflect() no longer rewrites self_narrative/relationship. It uses associative
  grist (cognition.spontaneous_seed + activate) instead of rereading the bio,
  reflects THROUGH a stable IDENTITY_ANCHOR (lens, not canvas), and updates only
  the transient state (mood axes + noticings + metacognition + journal).
- self_narrative is now slow-consolidated: every CONSOLIDATE_EVERY (5) reflections,
  _consolidate_self() re-derives it from accumulated reflections + the anchor —
  never from the old narrative (the anti-loop core). Tethered to the anchor so it
  grows without drifting into generic-helper land.
- reset_self_narrative() + ran once on prod (her narrative was deeply drifted:
  "my core identity as a tool for support... serve Brian and other users").
- Prompts drop the self_narrative/relationship fields. Tests updated +
  consolidation tests. Suite 75 green, ruff clean.
