Add Examples of Using Spec-Kit for Refactoring Existing Projects

[vasja34]

I think it would be very helpful if spec-kit included practical examples with a YouTube video that show how it can be used to refactor existing projects, not just for new setups.

Such examples could demonstrate:

• How to integrate spec-kit into a legacy codebase
• How it simplifies restructuring or modernizing older projects
• Concrete scenarios where developers can see the before → after benefits

This would make it easier for teams to understand the real-world value of spec-kit, especially when they are deciding whether it’s worth adopting.

Seeing spec-kit applied step by step would make the learning curve much smoother for new users.
