Large project typescript performance tests

[riordanpawley]

Hey, I mentioned this in the effect discord but I wanted to add an issue, and potentially contribute if you're interested.

I think it's important to verify/test the performance of typescript when using foldkit for apps with thousands of commands.

Have you thought about this further/would you be interested in a PR?

Would be very interested in a PR if you'd like to contribute one @riordanpawley! Thank you!

Something to consider is that large apps will have submodels/submessages: https://github.com/devinjameson/foldkit/blob/main/examples/shopping-cart/src/main.ts#L57
