// Next 15+ server-side instrumentation entry. Next calls `register()`
// exactly once per server boot, before the first request. We dispatch to
// the runtime-specific Sentry init so the Node + edge SDKs each get
// loaded only in the environment they target.
//
// The `onRequestError` hook (also Next 15+) forwards uncaught RSC /
// route-handler / server-action errors to Sentry's `captureRequestError`
// helper, which adds Next-aware breadcrumbs (routerKind, routeType,
// renderSource) that bare `Sentry.captureException` would miss.
