Error when creating response on global scope (outside fetch)

I came across the following tweet:

Words from SaltyAom:

```
Basically you are not allow to define a Response outside of the “fetch” handler in Cloudflare Worker
Which means you can’t create Response beforehand then clone when you actually need it
Elysia relies on this behavior for many plugin and the inline API as well

What’s annoying is that this niche error has caused at least multiple issues in various libraries
Nextjs, Astro Cloudflare Adapter, even Hono
Try “cloudflare worker disallowed operation called within global scope”
There’s literally 0 documentation even direct link from the error
```

It's possible to fix this since it could lead to add support to Elysia?
