AX Agent 도구·스킬 정합성 재구성 및 실행 품질 보강

변경 목적:
- AX Agent의 도구 이름, 내부 설정, 스킬 정책, 실행 루프 사이의 불일치를 줄이고 전체 동작 품질을 높인다.
- claw-code 수준의 일관된 동작 품질을 참고하되 AX 구조에 맞는 고유한 카탈로그·정규화 레이어로 재구성한다.

핵심 수정사항:
- 도구 canonical id, legacy alias, 탭 노출, 설정 카테고리, read-only 분류를 중앙 카탈로그로 통합했다.
- ToolRegistry, AgentLoopService, 병렬 실행 분류, 권한 처리, 훅 처리, 스킬 allowed-tools 해석이 같은 이름 체계를 사용하도록 정리했다.
- Agent 설정/일반 설정/도움말의 도구 카드와 훅 편집기, 스킬 설명을 현재 런타임 구조에 맞게 갱신했다.
- 컨텍스트 압축, intent gate, spawn agents, session learning, model prompt adapter, workspace context 관련 변경과 테스트 추가를 함께 반영했다.
- 문서 이력과 비교/로드맵 문서를 최신 상태로 갱신했다.

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