release: v0.9.0 — BM25 하이브리드, Supersede, 자동 청킹, PPR edge 가중치, ruff CI 정리

## 코어 개선
- BM25 하이브리드 스코링 (corpus 크기 적응형)
- Supersede 감지 (같은 title 최신 우선)
- add_document() 자동 청킹 API
- PPR edge type별 차등 가중치 (CAUSED 1.0 > RELATED 0.4)
- kind soft boost (하드필터 → 1.5x 부스트)
- phrase 노드 검색 결과 필터
- evidence threshold 0.2→0.3 + 첫 문장 bias

## 벤치마크
- 외부 데이터셋 14종, LongMemEval (ICLR 2025)
- PPR/Evidence/PhraseExtractor 단위 테스트 67건
- Ablation S8 LLM Full

## CI
- ruff check + format 통과
- 318 tests passed
