AX Agent 프리셋 렌더와 주제 선택 흐름을 분리해 메인 창 책임을 줄인다

- ChatWindow.TopicPresetPresentation을 추가해 프리셋 카드 생성, 커스텀 프리셋 메뉴, 주제 선택 적용 흐름을 별도 프레젠테이션 계층으로 이동한다

- ChatWindow.xaml.cs에서는 프리셋 UI 조립 코드를 제거하고 대화 orchestration 중심 구조를 더 강화한다

- claw-code parity plan과 개발 문서에 구조 개선 진행 상황을 반영해 큰 구조 개선 항목이 사실상 마감 단계임을 기록한다

- 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 09:44 (KST) - At this point the completed structure-improvement items are: status presentation cataloging, permission/tool-result catalog enrichment, permission UI cleanup, and ask/plan renderer separation. The remaining larger tracks are footer/composer work-bar refinement and enforcing the regression prompt ritual in day-to-day development.
 - Document update: 2026-04-06 09:58 (KST) - Split Git branch popup assembly and footer-adjacent summary helpers out of `ChatWindow.FooterPresentation.cs` into `ChatWindow.GitBranchPresentation.cs`. The footer presentation partial now focuses on folder-bar state and selected-preset guide synchronization instead of mixed popup rendering.
 - Document update: 2026-04-06 09:58 (KST) - Rewrote `docs/AX_AGENT_REGRESSION_PROMPTS.md` into a repeatable regression ritual with explicit failure classes (`blank-reply`, `duplicate-banner`, `bad-approval-flow`, `queue-drift`, `restore-drift`, `status-noise`) and required prompt bundles per change area so runtime/transcript work can be validated consistently.
+- Document update: 2026-04-06 10:07 (KST) - Split topic preset rendering and selection flow out of `ChatWindow.xaml.cs` into `ChatWindow.TopicPresetPresentation.cs`. Preset card creation, custom preset dialogs/context menus, and `SelectTopic(...)` metadata application now live in a dedicated partial.
+- Document update: 2026-04-06 10:07 (KST) - This keeps the main chat window more orchestration-focused and narrows the remaining maintainability work to small follow-up polish rather than any large structural split.

 - Continued the maintainability track by splitting Git branch popup and footer-adjacent summary helpers into `ChatWindow.GitBranchPresentation.cs`, leaving `ChatWindow.FooterPresentation.cs` focused on folder bar state and preset-guide sync only.
 - Formalized the regression ritual in `docs/AX_AGENT_REGRESSION_PROMPTS.md` by adding failure classes (`blank-reply`, `duplicate-banner`, `bad-approval-flow`, `queue-drift`, `restore-drift`, `status-noise`) and required prompt bundles per change area.
+- Updated: 2026-04-06 10:07 (KST)
+- Continued the maintainability track by moving topic preset rendering, custom preset context menus, and topic-selection application flow into `ChatWindow.TopicPresetPresentation.cs`. This reduces mixed preset UI logic inside `ChatWindow.xaml.cs` and keeps the main window closer to orchestration-only responsibility.
 
 ## Preserved History (Summary)
 - Core loop guards and post-tool verification gates are already partially implemented.
