도구·권한·스킬 표현 정교화 1차 반영

- 권한 요청 카탈로그를 bash/powershell/web_fetch/mcp/skill/file_edit/file_write/git/document/filesystem 수준으로 세분화했습니다.

- 도구 결과 카탈로그에 approval_required, partial, follow-up hint, attention 메타를 추가해 후속 renderer 고도화 기반을 마련했습니다.

- 스킬 갤러리에 모델, 추론 강도, 실행 컨텍스트, 에이전트, 모델 호출 비활성화, 추천 상황을 표시하도록 확장했습니다.

- README, DEVELOPMENT, parity plan, regression prompts 문서를 2026-04-06 11:52 (KST) 기준으로 갱신했습니다.

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

 - Document update: 2026-04-06 11:27 (KST) - At this point preview, file browser, worktree chooser, and permission-mode popup surfaces all share nearly the same visual language; remaining work is minor spacing/color polish rather than another behavior or structure change.
 - Document update: 2026-04-06 11:34 (KST) - Added `FooterChipBtn` to `ChatWindow.xaml` and aligned the footer work-bar buttons (`권한`, `Git 브랜치`) to the same rounded border, padding, and hover language instead of mixing outline and ghost button styles.
 - Document update: 2026-04-06 11:34 (KST) - This is a footer polish follow-up after the structure split, aimed at making the bottom work bar feel like one coherent tool row rather than a set of unrelated controls.
+- Document update: 2026-04-06 11:52 (KST) - Expanded `PermissionRequestPresentationCatalog.cs` into an action-level permission taxonomy (`bash`, `powershell`, `command`, `web_fetch`, `mcp`, `skill`, `question`, `file_edit`, `file_write`, `git`, `document`, `filesystem`) and added `ActionHint`, `Severity`, `RequiresPreview` metadata for later renderer refinement.
+- Document update: 2026-04-06 11:52 (KST) - Expanded `ToolResultPresentationCatalog.cs` with richer result taxonomy and post-result guidance. AX now distinguishes `approval_required` and `partial` in addition to `success / error / reject / cancel`, and each result carries `FollowUpHint` and `NeedsAttention`.
+- Document update: 2026-04-06 11:52 (KST) - Extended `SkillGalleryWindow.xaml.cs` to expose runtime-policy metadata (`model`, `effort`, `execution context`, `agent`, `disable model invocation`, `when to use`) so AX skills are easier to inspect and maintain like `claw-code` bundled skills.
