spec+plan(v0.17.0): korean trigram tokenizer + dogfood fixes
P10 도그푸딩 round 2 (2026-05-22) follow-up. SQLite FTS5 tokenizer
unicode61 → trigram 으로 교체해 한국어 lexical 검색 지원 + 작은
버그픽스 2 (C typedef-wrapped struct 미노출, code_lang_breakdown
집계 단위).
Codex + Gemini round 1/2/3 리뷰 반영:
- [r1] 2자 한국어 query 0-hit, build_match_string() multi-token 깨짐,
contentless → shadow, parser_version cascade, BM25/heading_path/디스크
- [r2] same-workspace_path orphan purge (parser bump cascade 실제 동작),
trigram 테스트 예시 sqlite 3.45.1 검증, builder 권장안 (whole phrase OR)
- [r3] SMOKE 시나리오 정정, TUI stale hint 방지, search_response.v1 hint
필드, new purge helpers, single quote raw mode 통일, fixture 도입
PR 구성: PR-A (trigram + builder + 안내), PR-B (C typedef + orphan
purge), PR-C (stats + wire). 셋 머지 후 v0.17.0 release cut.
