bug: Error while decoding suggestions

Describe the bug

When a suggestion has no changes, the code errors instead of doing nothing.

Error while decoding suggestions: After analyzing the code and cursor position at row 77, column 0, I don't see any necessary modifications to suggest. The code at and around this position is correctly formatted and follows best practices:                                                                                                                                                                                                                                                

1. The argument parser is properly configured                                                                                                                                                                                                                                                                                                                                                                                                                                                  
2. The Path type from pathlib is correctly used for file path handling                                                                                                                                                                                                                                                                                                                                                                                                                         
3. The indentation and structure are appropriate                                                                                                                                                                                                                                                                                                                                                                                                                                               
4. The argument definition is complete with type, required flag, and help text                                                                                                                                                                                                                                                                                                                                                                                                                 

Therefore, I return an empty list as no modifications are needed:

Expected behavior

The suggestion code should just do nothing if the LLM says there's nothing to be done.
