 * Node.js ESM resolve hook used by the CORS verification harness.
 *
 * Next.js ships no package.json "exports" map, so the canonical bare specifier
 * `next/server` does not resolve under raw Node ESM (the Next.js bundler
 * resolves it itself). This hook maps it to the actual CJS file so the
 * middleware module under test (src/lib/http/cors.ts, which imports
 * `next/server`) can be loaded by plain `node` for verification.
