feat(node)!: Remove import-in-the-middle ESM loader and deprecated instrumentation base

MIGRATION.md

@@ -351,7 +351,8 @@ Sentry.init({
 - The deprecated `honoIntegration` was removed. Use the [`@sentry/hono`](https://www.npmjs.com/package/@sentry/hono) SDK to instrument Hono.
 - The `connect` instrumentation was removed.
 - The deprecated `prismaInstrumentation` option was removed. It was no longer used, as Prisma works out of the box.
-- The deprecated `SentryHttpInstrumentation` export was removed. Use `instrumentHttpOutgoingRequests()` instead.
+- The `registerEsmLoaderHooks` option was removed. All instrumentation is now channel-based (via `@sentry/server-utils`), so the SDK no longer registers `import-in-the-middle` ESM loader hooks and the option no longer had any effect.
+- The deprecated `SentryHttpInstrumentation` and `SentryNodeFetchInstrumentation` exports were removed. Use `instrumentHttpOutgoingRequests()` and the `nativeNodeFetchIntegration` respectively.
 - (Fastify) The deprecated `setShouldHandleError` method was removed.
 - (AWS Lambda) The deprecated `disableAwsContextPropagation` option was removed. It no longer had any effect.
 - (AWS Lambda) The deprecated `startTrace` option was removed. It no longer had any effect; to disable tracing, set `tracesSampleRate` to `0`.

-/**
- * This custom HTTP instrumentation handles outgoing HTTP requests.
- *
- * It provides:
- * - Breadcrumbs for all outgoing requests
- * - Trace propagation headers (when enabled)
- * - Span creation for outgoing requests (when createSpansForOutgoingRequests is enabled)
- *
- * Span creation requires Node 22+ and uses diagnostic channels to avoid monkey-patching.
- * By default, this is only enabled in the node SDK, not in other runtime SDKs that reuse this instrumentation.
- *
- * Important note: Contrary to other OTEL instrumentation, this one cannot be unwrapped.
- *
- * This is heavily inspired & adapted from:
- * https://github.com/open-telemetry/opentelemetry-js/blob/f8ab5592ddea5cba0a3b33bf8d74f27872c0367f/experimental/packages/opentelemetry-instrumentation-http/src/http.ts
- *
- * @deprecated This will be removed in v11. Use instrumentHttpOutgoingRequests() instead.
