chore: sync working tree — Stage 1 v.7 reorg, jikji indexes, claim-drafting docs

- Rename "Claude YAML"/"Codex YAML" folders to Claude_YAML/Codex_YAML in Stage_1 v.7
- Add Stage_1 v.7 extension research, results runs, and reference material
- Add/refresh .jikji search indexes (Case_02 and Default_Agent corpora)
- Add per-case-type claim drafting folders and PDFs (청구취지기재방법)
- Add 판례모음 crawling data (08_14, 08_18)

+런타임 단축 목표까지 포함하면 한 가지 추가 분기가 있습니다
+파생 audit 제거만 해도 C2는 가벼워지지만, 가장 큰 출력량은 canonical_bo_decisions의 skeleton seed입니다
+C3가 C0를 읽어 skeleton을 확장할 수 있는지 확인해서, 전략에 “필수 1차”와 “확장 1차” 경계를 정확히 넣겠습니다
