[bug] Response.clone() headers lost with tauri-http-fetch

### Describe the bug

The `Response` created by the tauri-http-fetch plugin overrides `.headers` using `Object.defineProperty` instead of passing headers into the `Response` constructor. Because of this, `response.clone().headers` is empty even though the original response has headers.

### Reproduction

1. Use tauri-http-fetch to fetch a request with headers.
2. Pass the response into ky.
3. In a hook, clone the response: `const clone = response.clone()`.
4. Inspect `clone.headers`: it’s empty even though `response.headers` has entries.

### Expected behavior

Headers should be carried through cloning. After calling `response.clone()`, all headers from the original should be present on the cloned response.

### 🛠 Fix suggestion

Construct the response like this:
```js
const res = new Response(body, {
status,
statusText,
headers: responseHeaders
});
Object.defineProperty(res, 'url', { value: url, enumerable: true });
return res;
