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)

+# Jikji LLM Wiki Schema
+
+Status: deterministic local schema v1
+
+## Layers
+
+1. Raw source files stay in their original local paths and are never moved.
+2. `.jikji/doc_text/` stores parser text caches for supported documents/media.
+3. `.jikji/wiki/` stores compact markdown source pages for agent reading.
+4. `.jikji/knowledge_graph.json` stores a typed graph of corpus/source/folder/term/intent/duplicate nodes.
+5. `.jikji/graph_routes.jsonl` stores one low-token route row per source for fast file discovery.
+
+## Edge kinds
+
+- `contains_folder`
+- `contains_source`
+- `folder_contains_source`
+- `mentions`
+- `has_intent`
+- `folder_has_intent`
+- `member_of_duplicate_group`
+
+## Safety
+
+All artifacts are generated.  They may contain source-derived sensitive text snippets.  Jikji must never edit, move, rename, or delete original files while compiling this wiki.
