// vscode-jsonrpc is CJS and uses require("util") etc. When bundled into
// ESM, esbuild's __require polyfill throws because `require` is undefined.
// Providing a real require via createRequire fixes this for Node built-ins.
// Use alias (__bannerCreateRequire) to avoid colliding with cli.ts's own
