Function getOriginalFetch

getOriginalFetch(): (
input: string | URL | Request,
init?: RequestInit,
) => Promise<Response>
Return the un-instrumented fetch function.

If instrumentFetch (or the Cloudflare instrument() helper that calls it internally) has been used, this returns the original reference captured before the monkey-patch was applied.

Falls back to globalThis.fetch when no instrumentation has occurred.

Returns (input: string | URL | Request, init?: RequestInit) => Promise<Response>
Example
```
import { getOriginalFetch } from "@tigorhutasuhut/telemetry-js";

// Always hits the network without creating a span:
const res = await getOriginalFetch()("https://collector.example.com/v1/traces", { method: "POST", body });
```
