Chromium idle-terminates the Service Worker while its tab is backgrounded, which wipes the worker's in-memory active-client registry even though the page's worker/registration is still alive. The next request from that tab then silently falls through to the real network until a full reload re-runs the MOCK_ACTIVATE handshake. Add MockingGUIWorkerManager.reactivate(), which re-sends that same handshake on the existing worker, and call it from a visibilitychange listener so mocking recovers as soon as the tab is visible again, without requiring a reload.

백그라운드에 있던 탭이 돌아왔을 때 mocking이 조용히 실제 API로 풀리는 문제를 수정했습니다. 브라우저가 유휴 상태의 Service Worker를 종료시키면서 메모리에 있던 활성 클라이언트 상태가 사라지는데, visibilitychange 시점에 MOCK_ACTIVATE 핸드셰이크를 재전송하여 새로고침 없이도 mocking이 복구되도록 했습니다.
