Automated Code Review Assistant

## Setup Guide

1. **GitHub Trigger**: Connect your GitHub account and specify the repository owner and name to listen for new Pull Requests.
2. **Get PR Files**: This node fetches the file content. You might need to adjust this to loop through multiple files if needed (simplified here for single file context).
3. **AI Code Review**: Add your OpenAI API Key. The prompt is set to act as a Senior Engineer.
4. **Post Comment**: This posts the AI's analysis back to the original PR as a comment.
