perf: 全量识别 schedule 路径加 30 秒节流

修复 dynamic-snapshot 死循环后仍观察到 page-detector 每 12-23 秒被重新注入、每次同步阻塞主线程 1.5+ 秒。scheduleActivePageDetection 在距离上次成功跑过不到 30 秒时跳过排程，让 tabs.onUpdated 反复触发 complete 等情况下不再堆积全量识别。tab loading/removed/url 不支持时清掉 throttle，确保 F5 刷新和切换页面仍能正常重检；用户主动重检走 message-router 直调 runActivePageDetection 不受节流。将版本号提升到 1.2.85。
