docs: initial spec, v0-plan, brainstorming, CLAUDE.md harness rules

- docs/spec.md: 정식 spec (브랜드·시장·기술 스택·일정·Day 0 검증 결과)
- docs/v0-plan.md: W1~W4 13 task 구현 plan (TDD + manual test 절차)
- docs/brainstorming-raw.md: 2026-05-23 brainstorming 원본
- CLAUDE.md: 하네스 운영 규약 (컨텍스트 3단·agentic 7 구성요소·박재오 Why 정합도)
- README.md: 입구 + v0 상태 표
- .gitattributes: Windows ↔ macOS LF 통일 + pbxproj 바이너리 처리
- src/, modules/ 폴더 구조 (.gitkeep)

박재오 + AI agent 협업 표준 정립. 7월 착수 → 5/24 앞당김.
