+Migrate the pi agent, model, and coding-agent packages together to the maintained 0.79.x releases (at least 0.79.0), which fix extension loading, credential-file, and HTML-export security issues. Align the application's HTTP runtime with pi's fixed Undici 8.12.4 release and require Node.js 22.19.0 or newer.
