AX Agent transcript 품질 향상과 회귀 기준 정리

- 도구/스킬 transcript 표시 카탈로그를 분리해 파일, 빌드, Git, 문서, 질문, 제안, 스킬 분류를 공통 라벨로 통일함
- task summary popup을 active 우선, recent/debug 보조 기준으로 축소하고 transcript policy helper를 partial로 분리함
- AX Agent와 claw-code 비교용 회귀 프롬프트 세트를 별도 문서로 추가하고 관련 개발 문서를 즉시 갱신함
- 검증: dotnet build src/AxCopilot/AxCopilot.csproj -c Release -v minimal -p:OutputPath=bin\\verify\\ -p:IntermediateOutputPath=obj\\verify\\ (경고 0 / 오류 0)
