상태선/권한 카탈로그 구조 정리와 계획 모드 표현 잔재 제거

- OperationalStatusPresentationCatalog를 추가해 compact strip과 quick strip의 색상/노출 계산을 AppStateService 밖으로 분리함

- PermissionRequestPresentationCatalog와 ToolResultPresentationCatalog에 Kind/Description 메타를 추가해 transcript fallback 설명을 타입 기반으로 정리함

- PermissionModePresentationCatalog와 ChatWindow.PermissionPresentation에서 제거된 계획 모드 표현 분기를 걷어 권한 UI를 실제 지원 모드만 다루도록 단순화함

- README, DEVELOPMENT, claw-code parity plan 문서를 2026-04-06 09:36 (KST) 기준으로 갱신함

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

 - Current estimated parity vs `claw-code`: core execution engine `82%`, main chat UI `68%`, Cowork/Code status UX `63%`, internal settings linkage `88%`, overall AX Agent `74%`.
 - Engine-affecting settings should be handled conservatively during parity work. If a setting changes the main execution route, approval flow, or recovery behavior without representing a stable real-world user choice, it should be moved to developer-only UI or removed from user-facing surfaces.
+- Updated: 2026-04-06 09:36 (KST)
+- Progressed the maintainability track by moving runtime strip styling into `OperationalStatusPresentationCatalog.cs`, expanding permission/tool-result transcript catalogs with typed descriptions, and removing the stale plan-mode presentation branch from permission UI surfaces. The next structural focus remains footer/status/composer presentation slimming and regression ritual enforcement.
 
 ## Preserved History (Summary)
 - Core loop guards and post-tool verification gates are already partially implemented.
