 * Next.js Instrumentation Hook
 *
 * This file is automatically executed by Next.js at startup to initialize server-side SDKs.
 *
 * Configuration Flow:
 * 1. This file (instrumentation.ts) - Server-side initialization
 * 2. Runtime-specific configs:
 *    - sentry/sentry.server.config.ts (Node.js runtime)
 *    - sentry/sentry.edge.config.ts (Edge runtime)
 * 3. Client-side init:
 *    - instrumentation-client.ts (Browser/Client; reads the runtime data island)
 *
 * @see https://nextjs.org/docs/app/building-your-application/optimizing/instrumentation
