/**
 * Lifecycle Orchestrator — 트리거 이벤트 수신 → rule 상태 전이 적용.

 * 데이터 플로우:
 *   [T1~T5 + Meta] ─detect(state)→ LifecycleEvent[]
 *                                          │
 *          applyEvent(rule, event) ← ──────┘  (pure)

 *         ┌────────┴────────┐
 *    saveRule(rule)    persistEvent(event)
 *   (rule-store.ts)   (~/.forgen/state/lifecycle/{date}.jsonl)
 *
 * applyEvent 는 pure — rule → rule'. 부수효과는 saveRule / appendLifecycleEvents 에서만.
 *
 * 상태 전이 규칙 (ADR-002 §State transitions):
 *   flag        → phase='flagged'
 *   suppress    → phase='suppressed'  (+ status='suppressed')
 *   retire      → phase='retired'     (+ status='removed')
 *   merge       → phase='merged'      (+ merged_into)
 *   supersede   → phase='superseded'  (+ superseded_by)
 *   promote/demote_mech → phase 유지, meta_promotions 는 meta-reclassifier 가 직접 기록
