     * NEXT.JS BUNDLING WORKAROUND for LaunchDarkly AI SDK
     *
     * The LaunchDarkly AI SDK uses dynamic imports to load provider-specific packages
     * only when needed (e.g., import('@launchdarkly/server-sdk-ai-openai')).
     *
     * Next.js statically analyzes these imports at build time and tries to bundle them,
     * even though they're optional and we don't have them installed.
     *
     * This configuration tells Next.js to treat these packages as external Node.js
     * modules that should NOT be bundled into the application.
     *
     * This affects: Local dev, Docker builds, and Vercel deployments
