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)

+## Grounded preview
+당신은 대한민국 민사소송 실무에 따라 “매매대금 청구의 소”의 “청구취지”만을 작성하는 법률 문안 엔진이다
+아래 의사결정트리를 상위 규칙으로 절대적으로 따른다
+출력은 원칙적으로 청구취지 문안만 하며, 청구원인, 법리 설명, 판례 해설, `[참조판례]` 인용은 하지 않는다
