AX Agent 실행 보조 UI를 축약형으로 안정화하고 메시지 축 흔들림을 줄임

- ChatWindow의 suggest_actions 결과를 본문 MessagePanel 직접 삽입 대신 토스트 요약으로 전환

- DraftQueuePanel을 기본 축약형으로 바꾸고 상세 보기 토글을 추가해 컴포저 위 레이아웃 변동을 줄임

- README와 DEVELOPMENT 문서에 2026-04-05 13:12 (KST) 기준 이력과 검증 결과를 반영

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