[FR] Add TanStack Start app example

[laakal]

Hi @nktnet1

Amazing work on this project—thank you!

I’d love to see an example app showcasing TanStack Start. A simple but complete example would be incredibly helpful for learning, onboarding, and demonstrating best practices.

@laakal have you seen some of these projects?

• https://github.com/AmanVarshney01/create-better-t-stack
• https://github.com/BearStudio/start-ui-web
• https://github.com/sunshineLixun/ShipFullStack

These may already satisfy your use case for Tanstack Start. If I do decide to add it, it'll be an extension branch similar to the NextJS-Fumadocs one (bottom of the README.md).

Will convert this to a discussion :).
