Subject: [PATCH] feat: added support for creating multiple files using pattern
 {file1,file2,file3}.ext

- Added functionality to create multiple files at once using the pattern {file1,file2,file3}.ext
- Updated both action.create and action.create_from_prompt to use create_items for handling multiple files
- Users can now generate multiple files in one go, e.g., {index,about,contact}.html creates index.html, about.html, and contact.html.
