Five high-impact improvements to the memory system:
1. Min RRF score threshold on auto-recall (default 0.25) — filters low-relevance
results before injecting into context
2. Deduplicate auto-recall against core memories already present in context
3. Capture assistant messages (decisions, recommendations, synthesized facts)
with stricter attention gating and "auto-capture-assistant" source type
4. LLM-judged importance scoring at capture time (0.1-1.0) with 5s timeout
fallback to 0.5, replacing the flat 0.5 default
5. Conflict detection in sleep cycle (Phase 1b) — finds contradictory memories
sharing entities, uses LLM to resolve, invalidates the loser
