상위 AGENTS 지침 선행 읽기 순서 명시

[debop]

Summary

이번 PR은 모든 저장소 작업이 user-scope 및 workspace-scope 운영 지침을 먼저 읽도록 기준을 통일합니다.

Background

저장소별 AGENTS.md가 workspace 상속만 명시하거나 scope 순서를 직접 고정하지 않아, broader guidance가 누락될 수 있는 운영 공백이 있었습니다.

What This Solves

• user-scope와 workspace-scope AGENTS.md의 선행 읽기 순서를 workspace 기준 문서에 고정합니다.
• repo-local overlay가 broader guidance를 생략하지 않도록 공통 계층을 명확히 합니다.

Work Done

• .github/docs/workspace/AGENTS.md: user → workspace → repository/worktree 계층을 명시했습니다.
• .github/AGENTS.md: 저장소 overlay의 선행 읽기 규칙을 추가했습니다.

Validation

• git diff --check: PASS
• python3 .github/scripts/sync_workspace_docs.py --check: PASS
• cmp -s .github/docs/workspace/AGENTS.md AGENTS.md: PASS
