chore: 이전 세션이 남긴 변경을 커밋한다

이번 파이프라인 작업과 무관하게 작업 트리에 남아 있던 것을 그대로 올린다.
사용자가 「전부 커밋」으로 정했고, 이번 작업과 섞이지 않게 커밋만 나눴다.

대부분은 clean-architecture-backend-template 의 그림 정본 재배치다 —
final/assets/diagrams/<이름>/ 에 있던 것이 CLAUDE.md 가 적은 배치인
final/assets/<이름>/ 로 옮겨졌고 .techviz/<이름>/ 이 함께 들어왔다.
삽입 줄의 대부분(3.15M)이 그 .techviz context.json 이다.

그 밖에 ca-tmpl·document-haness 의 정리, .claude/agents/ 열한 개,
writing-practitioner-guides 스킬, .playwright-mcp 세션 산출물,
scripts/check-ssot-facts.py 와 그 시험이 들어 있다.

이 커밋의 내용은 내가 만든 것이 아니라 이전 세션이 남긴 것이고 검증하지 않았다.
