修复巡检报告快照可能多次生成的竞态:

1. reportScheduler._inProgress —— 快照执行 >60s 时,
   下一个 tick 进来直接跳过,防止定时 tick 重入
2. index.cjs._isSnapshotRunning 双向互斥 ——
   reportScheduler.tick 和 IPC 手动触发路径互相感知,
   谁先进来谁锁,另一条路径跳过
3. IPC inspection:runReportSnapshot 入口拦截 ——
   用户连点"立即巡检"按钮被拒绝

之前已修:renderer scheduler:start 不再触发 scanAllNow。
