- 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)
