AX Agent 질문/의견 요청 흐름을 transcript 우선으로 전환

- user_ask 콜백을 별도 팝업 대신 본문 inline 카드 경로로 변경
- 선택지 pill, 직접 입력, 전달/취소 버튼을 timeline 안에서 처리
- 계획 승인과 질문 요청이 같은 transcript-first UX 원칙을 따르도록 정리
- claw-code parity 문서와 개발 이력 문서에 질문/승인 UX 기준을 반영

 # AX Copilot - 媛쒕컻 臾몄꽌
 
+- Document update: 2026-04-05 18:58 (KST) - Switched `UserAskCallback` in `ChatWindow.xaml.cs` to a transcript-first inline card flow. `user_ask` no longer defaults to `UserAskDialog`; it renders an in-stream question card with choice pills, direct text input, and submit/cancel actions, then returns only the chosen answer to the engine.
+- Document update: 2026-04-05 18:58 (KST) - Aligned user-question UX with the same transcript-first principle already used for plan approval. `PlanViewerWindow` remains a secondary detail surface, while the primary approval/question decision now happens inside the AX Agent message timeline.

 - Document update: 2026-04-05 16:55 (KST) - Recorded the current `claw-code` parity estimate for AX Agent: core execution engine `82%`, main chat UI `68%`, Cowork/Code status UX `63%`, internal settings linkage `88%`, overall AX Agent parity `74%`.
 - Document update: 2026-04-05 16:55 (KST) - Added an engine-settings review rule for ongoing cleanup: settings that materially alter the main execution route should be minimized, kept developer-only when necessary, or removed from user-facing surfaces when they no longer represent real runtime choices. Plan-mode remnants were reduced further as part of this pass.
 - Document update: 2026-04-05 16:55 (KST) - Simplified AX Agent message rows and sidebar conversation items toward the `claw-code` reading model. Message bubbles now use tighter padding/radius/meta text, and conversation rows now prefer lightweight running/failure summary text over heavier success/failure badge cards.
