Code Review

This pull request adds the 'Bob's Brain' project to the community showcase. The project is a great example of a production-grade ADK implementation. My review includes a couple of suggestions to align the new entry's formatting with the existing projects on the page for better consistency. Specifically, I've recommended shortening the title and condensing the detailed description into a single paragraph, similar to the other featured projects.
