Issue: Limited Scope for Running the Tool on Changed Files in Pull Requests

The current version of the tool is impressive and has proven to be useful. However, it lacks the ability to run exclusively on the files that have been modified in a pull request. This feature is crucial for legacy projects, as they tend to generate numerous errors when the tool is applied globally.

I believe this enhancement would greatly improve the usability and effectiveness of the tool, especially for those working on older projects.
