DongHyeonkaandClaude Opus 5 3e2406349a contract: studio 계약의 VALIDATION_FAILED 개명(DOCUMENT_VALIDATION_FAILED) 반영
canonical studio-v1.yaml(tech-log-design-package b20d7a2)이 VALIDATION_FAILED를
DOCUMENT_VALIDATION_FAILED로 개명했다 — 스켈레톤 전역 OperationalError.
VALIDATION_FAILED(400)와 code 문자열이 충돌해 같은 code가 두 HTTP status를
갖던 문제를 해소한다.

- generate:tech-log-contract로 vendor된 계약·생성 타입·canonical-source.json 재생성
- STUDIO_ERROR_CODES(손수 유지되는 계약 미러)의 해당 항목 개명

계약 밖 코드는 STUDIO_UNAVAILABLE로 접히므로 이 배열이 계약과 어긋나면 안 된다.
