Subject: [PATCH] chore(scripts): enhance commit message generation with
 additional file data

Included the reading of file contents directly in the `commit` function to provide a more comprehensive context for commit message generation. This addition will help in producing more accurate and context-aware commit messages by utilizing the contents of the files that are staged for commit. The implementation leverages the `readFileSync` method to gather the necessary data, ensuring all relevant file information is available during the commit message generation process.
