@arkxio/ark-iso

当 @arkxio/ark-micro、@arkxio/ark-micro-core 包体被提升到 exnternal 里载入时，isSubApp判断会失效，可独立安装此包来调用 isSubApp 函数

bofore

import { isSubApp } from '@arkxio/ark-micro';
// or
import { isSubApp } from '@arkxio/ark-lib-proxy';

after

import { isSubApp } from '@arkxio/ark-iso';
// or just import in entry file first line
import '@arkxio/ark-iso';

// then you can call isSubApp that can return right result in any other files
