AX Agent 계획 승인 흐름과 상태선 표현 계층 정리

- 계획 승인 기본 흐름을 transcript inline 우선 구조로 더 정리하고, 계획 버튼은 저장된 계획을 여는 상세 보기 성격으로 분리했습니다.

- OperationalStatusPresentationState를 확장해 runtime badge, compact strip, quick strip의 문구·강조색·노출 여부를 한 번에 계산하도록 통합했습니다.

- ChatWindow 상태선/quick strip/status token 로직을 StatusPresentation partial로 분리해 메인 창 코드의 직접 분기와 렌더 책임을 줄였습니다.

- 문서 이력(README, DEVELOPMENT)을 2026-04-06 01:37 KST 기준으로 갱신했습니다.

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