+- AX Agent 좌측 대화 목록 상태 심볼을 열린 링에서 꽉 찬 원형 구체 스타일로 정리했습니다. `src/AxCopilot/Views/ChatWindow.xaml`의 `ConversationItemTemplate`에서 idle/running 상태 표시를 스트로크 기반 `Ellipse` 대신 레이어드 원형 배지로 교체해 한쪽이 비어 보이던 인상을 없앴습니다.
+- idle 상태는 중립색 구체와 하이라이트로, 실행 중 상태는 `AccentColor` 기반 구체로 표시되게 바꿨고, unread completion 점도 같은 시각 언어에 맞춰 외곽 스트로크와 하이라이트를 맞췄습니다.
