`useDebounce` 选项 `leading` 不能正常工作

[junerver]

if ((isMaxWait && calledCount != 0) || (calledCount == 0 && leading)) {
    task(guarantee = true, isDelay = false)
} else {
    if (calledCount > 0 && interval < wait) {
        clear()
        if (trailing) {
            task(guarantee = false, isDelay = true)
        }
    } else {
        task(guarantee = false, isDelay = true)
    }
}

由于通过calledCount == 0 && leading 判断执行了保障任务， leading 只在第一次防抖执行时工作，后续即使已经解除防抖，也不能正常触发 leading
