BlockingEvent class

主线程阻塞事件 / Main-thread blocking event

一次"心跳超时"代表 UI isolate 在 durationMs 内没能响应心跳定时器， 通常是同步重活（大 JSON 解析、密集 build）、锁等待或平台通道阻塞。 A heartbeat timeout means the UI isolate failed to answer the watchdog timer for durationMs — usually a heavy synchronous task (big JSON parse, dense build), a lock wait, or a blocked platform channel.

Constructors
