The standalone next package is trimmed and doesn't include webpack. The custom server.js was using next() which triggers config loading that requires webpack. Fix by extracting the standalone config at build time and setting __NEXT_PRIVATE_STANDALONE_CONFIG before requiring next, matching what the generated standalone server does.
