/**
* ESM instrumentation registration for Node.js 18.19+
*
* This module registers the OpenTelemetry ESM loader hook using the modern
* node:module register() API. This eliminates the need for NODE_OPTIONS or
* --experimental-loader flags.
*
* Usage in instrumentation.mjs:
* ```typescript
* import 'autotel/register';  // MUST be first import!
* import { init } from 'autotel';
*
* init({
*   service: 'my-app',
*   instrumentations: [...],  // or autoInstrumentations: ['express', 'http', 'pino']
* });
* ```
*
* Then run:
* ```bash
* node --import ./instrumentation.mjs src/index.js
* # or with tsx:
* tsx --import ./instrumentation.mjs src/index.ts
* ```
*
* No NODE_OPTIONS or --experimental-loader needed!
*
* @requires Node.js 18.19.0 or later
* @see https://github.com/open-telemetry/opentelemetry-js/blob/main/doc/esm-support.md
* @see https://nodejs.org/api/module.html#moduleregisterspecifier-parenturl-options
