모델별 time-based compact 기준과 compact 메타 노출을 경량화

- service:model 조합별로 time-based tool_result 정리 기준을 분리해 Claude는 보수적으로, Qwen/vLLM 계열은 빠르게 오래된 결과를 걷어내도록 조정 - compact 메타 카드를 제목과 한 줄 요약 중심으로 단순화해 transcript 운영 노이즈를 축소 - README와 DEVELOPMENT 문서에 2026-04-12 22:19 (KST) 기준 작업 이력 반영 - 검증: dotnet build src/AxCopilot/AxCopilot.csproj -c Release -v minimal -p:OutputPath=bin\verify\ -p:IntermediateOutputPath=obj\verify\ (경고 0, 오류 0)
