当eventLoop设置为Workerman\Events\Swoole::class时候，静态文件访问出现异常


经测试当Webman开启协程的时候，且在Swoole驱动下，使用Webman原生的静态文件功能。

并且当文件较大时，浏览器访问这个文件，会出现这个异常。

小文件没有问题，我本地这张图片8M，出现了这个问题。

`server.php`中的`max_package_size`已经设置到了`1024 * 1024 * 1024`仍然未解决

Reproduce the failure with Webman coroutines enabled, the Workerman\Events\Swoole event loop, and a large static file; review server.php and the native static-file handling involved in that path. Verify the behavior with an 8 MB or larger file and confirm that large-file browser requests complete without the reported exception while small files still work.
