Code Review

This pull request adds .DS_Store to the .gitignore file, which is a good practice to prevent macOS-specific metadata files from being tracked by version control. My review includes a suggestion to expand the macOS-specific rules to be more comprehensive, which will improve the long-term maintainability of the repository by ignoring other common system-generated files.

[gemini-code-assist]

While adding .DS_Store is a good step, it's a common practice to include a more comprehensive list of macOS-specific files to prevent other system-generated files from being accidentally committed. This will make the .gitignore file more robust for all developers using macOS.
