Research direction

The issue body is empty, so the first step is to clarify the scope of the update. Review the existing bootlint rules to understand how they detect Bootstrap v3 patterns. Then, study Bootstrap v4's new classes, components, and markup changes. Check the repository's contributing guidelines and any related discussions in the comments. A good starting point would be to search for 'v4' in the codebase and comment threads to gather requirements.
