런처 클립보드 붙여넣기 포커스 복원 경로 통일

- 클립보드 히스토리, 클립보드 변환, 순차 붙여넣기 실행 경로에 공통 포커스 복원 helper를 추가했습니다. - 이전 활성 창 복원, 최소 대기, Ctrl+V 주입 순서를 하나로 맞춰 포커스 누락으로 내용이 원래 창에 들어가지 않던 문제를 완화했습니다. - 관련 변경 이력을 README와 DEVELOPMENT 문서에 반영했습니다. 검증: - dotnet build src/AxCopilot/AxCopilot.csproj -c Release -v minimal -p:OutputPath=bin\verify\ -p:IntermediateOutputPath=obj\verify\ - 경고 0 / 오류 0
