hyungi fa82bd495b feat(search): hier persist + partial ivfflat index on in_corpus (Hier-Decomp-1 c4)

persist_hier_tree(): build_hier_tree → document_chunks insert. source_type=hier_section,
in_corpus=false, is_leaf 노드만 bge-m3 embedding. idempotent(기존 hier 행 삭제 후 재삽입).
chunk_index = doc 별 (max+1) offset → 기존 (doc_id,chunk_index) unique 충돌 회피.
embedding NULL 파라미터 asyncpg 타입추론 → cast(cast(:emb AS text) AS vector) 이중캐스트.

migration 284/285: ivfflat 오염 fix. full 인덱스는 in_corpus=false hier 벡터까지 색인 →
근사 검색이 비활성 벡터에 오염(corpus_chunks 필터해도 근사 이웃 셋 흔들림). partial index
(WHERE in_corpus=true)로 교체 → in_corpus=false 는 검색 인덱스에 부재 = 무영향 인덱스 레벨 보장.

c4 pilot(5140/5186/5225) G3: 트리 insert, embed_coverage 1.0(doc-local 100%), in_corpus_true=0,
dangling_parent=0, dup 0. **부분인덱스 후 검색 baseline IDENTICAL to 원래(pre-hier)** = 691 hier
행 영향 0 검증(오염 fix 효과). replace 는 c5/c6.
