Simplify target repo projects path

[OziinG]

목적

CLEVER target repo 로컬 배치 규칙에서 불필요한 <project-slug> 중간 폴더를 제거한다.

요구사항

• target repo 경로를 <CLEVER_ROOT>/projects/<target-repo>/로 단순화한다.
• README, AGENTS, bootstrap skill, bootstrap Python packet, docs/setting, tests를 같은 구조로 맞춘다.
• 기존 root prompt도 새 경로를 안내하도록 갱신한다.

검증

• Python 테스트
• bootstrap script py_compile
• diff whitespace check

• GitHub checks: Validate static Pages site passed; deploy jobs skipped as expected for PR validation.

Remaining follow-up:

• Live fresh-root bootstrap clone into projects/<target-repo> was not run.
