Hyungi Ahn 5185501bbd feat(search): PR-RAG-Time-1 freshness decay (news/law_monitor)

뉴스/법령 알림 retrieval 결과에 시간 가중치 soft multiplier 적용.
reranker 이후 final score 합성 단계에서 운영 정책 단계로 분리.

- news (source_channel='news'): half-life 90일
- law_monitor (source_channel='law_monitor'): half-life 365일
- 비적용: manual / drive_sync / inbox_route / memo / Manual / Reference /
  Academic_Paper / Checklist / KGS Code / Study / content_origin='ai_drafted'
- formula: decay = exp(-ln(2) * age / HL); final = base * (0.7 + 0.3 * decay)
- floor 0.7 (완전 demote 금지)
- 가드: missing date / future date / unknown source 모두 no-op
- 임시 date source: documents.created_at (published_date 컬럼 부재 — 후속 PR)

debug 메타 (?debug=true 응답 + logs/search.log):
  base_score / age_days / decay_factor / freshness_adjusted_score /
  freshness_policy / freshness_date_source

신규: app/services/search/freshness_decay.py
hook: app/services/search/search_pipeline.py:303 (apply_diversity 직후, normalize 직전)
schema: app/api/search.py SearchResult.freshness_debug (Optional[dict])
tests: tests/test_freshness_decay.py 24 case (정책 디스패처 9 + age/decay/score 11 + apply integration 6 — guard 1~6 all)

Episode/Fact layer 와 contradiction detection 은 본 PR 스코프 외.
