Add code pair interview .cursorrules

[Roriz]

This Pull Request introduces a new .cursorrules file to enhance Cursor AI's code generation capabilities in the context of code pair programming interviews.

Purpose:

The added .cursorrules file provides specific guidelines to Cursor AI to produce code that aligns with the best practices and expectations commonly evaluated during code pair interviews. This includes:

• Clear code structure and organization (separation of concerns, modularity).
• Consistent coding style (indentation, naming conventions, comments).
• Adherence to general coding principles and style guides.
