/**
 * 巡检报告定时快照（全局 Hook）
 *
 * 挂载到 App.tsx 顶层 → 不管用户在哪个 Tab 都能定时跑快照，关页面（巡检报告 Tab）也不停。
 * 只有彻底关闭 Electron 应用才会停。
 *
 * 双路执行：
 *   - 主进程 reportScheduler（setInterval 1min）独立执行定时快照 + 日报告聚合
 *   - renderer 侧（本 Hook）负责：1) 把 vault 解密的 SSH 凭据同步给主进程；2) 作为兜底在 renderer 侧也执行 runSnapshot
 *
 * 为什么双路：
 *   - 主进程 scheduler 不依赖 renderer 是否打开监控页面 / Vault / 巡检报告页面
 *   - 但主进程没法解密 vault，必须由 renderer 在启动后（VaultPublisher 已解密）
 *     调 inspectionSchedulerApi.start(hostConfigs) 把凭据同步过去
