Jenkins 에이전트 연결 안정성 대폭 개선

- slaveConnectTimeout: 300초로 연결 타임아웃 설정
- activeDeadlineSeconds: 3600초로 Pod 최대 실행 시간 제한
- idleMinutes: 30분으로 에이전트 재사용 설정
- 컨테이너별 리소스 제한 추가 (podman: 1-2 cores, gradle: 0.5-1 core)
- hudson.remoting.RequestAbortedException 연결 에러 해결
- Context7 기반 Jenkins Kubernetes 플러그인 모범사례 적용
