Example 2048 game with nu-http as backend

[dadhi]

Server with examples using datastar - this is my fork:
https://github.com/dadhi/http-nu

I am interested in implementing the example of the game 2048 with dmax instead of datastar
https://github.com/dadhi/http-nu/tree/main/examples/2048

We need to do the new dm example alongside the ds, so we have a side by side comparison of implementation.
