+- feat(node)!: Remove `import-in-the-middle`-based instrumentations from `@sentry/node`. All performance integrations are now channel-based via `@sentry/server-utils`. As part of this:
+  - The `registerEsmLoaderHooks` option was removed from `NodeOptions`. The SDK no longer registers `import-in-the-middle` ESM loader hooks, and `import-in-the-middle` is no longer a dependency.
+  - `knexIntegration` and `dataloaderIntegration` are now channel-only and no longer fall back to OpenTelemetry instrumentation on runtimes without diagnostics-channel injection.
+  - Support for Fastify `<3.21.0` was dropped.

-/**
- * 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.
