Use in CloudFlare Workers - error with "cannot read from undefiend (trying to read 'href')

Nobody has claimed this yet.

This error suggests the package believes it's running in the browser when in fact it's running in Node (in my case, within CF Workers.)

This is when running the suggested demo code:

```
const { duktapeEval, quickjsEval } = require('wasm-jseval')
duktapeEval.getInstance().then(mod => {
console.log(mod.eval('1+1')) // 2
const add = mod.newFunction(['a', 'b'], 'return a+b')
console.log(add(1, 2)) // 3
})
```

Any thoughts here?

Start by reproducing the suggested duktapeEval demo from the issue in Cloudflare Workers and inspect where the `href` access occurs. Confirm whether the package's runtime detection selects browser behavior, then verify that the demo runs successfully in the Workers environment without the error.
