Improve .gitignore file to cover more common patterns

The current .gitignore file only includes the .DS_Store entry and may not be sufficient for typical development workflows. Consider updating the .gitignore to include additional patterns commonly ignored in collaborative or multi-platform projects, such as:
- IDE/editor files (e.g., .vscode/, *.swp)
- OS-specific files (e.g., Thumbs.db)
- Dependency directories (e.g., node_modules/)
