Instead of creating a stub onnxruntime-node module, patch the @xenova/transformers backend file to skip the onnxruntime-node import entirely and use only onnxruntime-web. This prevents the "Cannot read properties of undefined" error when the library tries to use the Node backend in a Node.js environment but only has the web backend available. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
