[Phase 44] LauncherViewModel·SettingsWindow.Tools·MarkdownRenderer 파셜 분할

LauncherViewModel (805줄 → 402줄, 50% 감소):
- LauncherViewModel.FileAction.cs (154줄): 파일 액션 서브메뉴, EnterActionMode, ExitActionMode
- LauncherViewModel.Commands.cs (273줄): CopySelectedPath, Favorite, Terminal, 클립보드 병합, INotifyPropertyChanged
- 오류 수정: FileAction.cs에 using AxCopilot.Themes 누락 → 추가

SettingsWindow.Tools (875줄 → 605줄):
- SettingsWindow.ToolCards.cs (283줄): AX Agent 서브탭 전환 + 도구 관리 카드 UI

MarkdownRenderer (825줄 → 621줄):
- MarkdownRenderer.Highlighting.cs (215줄): 구문 하이라이팅 전체 분리

빌드: 경고 0, 오류 0
