코드 탭은 컨텍스트만 claude-code식으로 두고 품질 게이트를 AX 기준으로 복원한다

- balanced와 reasoning_first 프로필에서 post-tool verification을 다시 활성화해 일반 코드 수정에도 후속 검증이 붙도록 조정

- bugfix/feature/refactor 작업에 구조화된 최종 보고 게이트를 다시 적용하고 Code 시스템 프롬프트의 VERIFY/REPORT 기준을 더 강하게 복원

- README와 DEVELOPMENT 문서 이력을 2026-04-13 00:08 KST 기준으로 갱신

- 검증: dotnet build src/AxCopilot/AxCopilot.csproj -c Release -v minimal -p:OutputPath=bin\\verify\\ -p:IntermediateOutputPath=obj\\verify\\ 경고 0 / 오류 0
