Code review the actual git branch using github copilot sdk.

A developer has built a script that uses the GitHub Copilot SDK to automatically review the actual git branch by sending the diff between main and HEAD to a large language model for analysis. The script generates a JSON file with review comments, including file paths and line numbers, following enterprise standards. The tool is designed to streamline code review processes by leveraging AI.
