권한 모드 동등화: Plan 추가 및 claw-code 권한 별칭 정규화 반영

- 전역 권한 모드를 Ask/Plan/Auto/Deny 4단계로 확장

- claw-code 계열 권한 값(default/acceptEdits/dontAsk/bypassPermissions) 입력 시 내부 모드로 정규화

- AgentContext 권한 판정 경로(전역/도구 오버라이드/패턴 오버라이드) 정규화 적용

- Chat/Settings UI에서 Plan 모드 노출 및 인라인 순환(Ask->Plan->Auto->Deny) 반영

- AppState/SettingsViewModel/SettingsService에 권한값 정규화 및 저장 시 일관성 적용

- Permission lifecycle 이벤트 메시지에 유효 모드 표기 보강

- 빌드/테스트 검증: dotnet build 경고0 오류0, dotnet test 372/372 통과
