Add the official React Compiler

[pataar]

This pull request adds the new, official, React Compiler to the starter kit.

React Compiler is a build-time tool that optimizes your React app through automatic memoization. React Compiler automatically optimizes your React application at build time. React is often fast enough without optimization, but sometimes you need to manually memoize components and values to keep your app responsive. This manual memoization is tedious, easy to get wrong, and adds extra code to maintain. React Compiler does this optimization automatically for you, freeing you from this mental burden so you can focus on building features.

I made sure all the React related dependencies are on a compatible version. The version of the React eslint plugin had some errors on a couple of hooks and components. I made changes accordingly. Happy to clarify any changes when needed.

Thanks for this PR! In testing I'm finding that the mobile hook is now firing quite a lot (the get snapshot function), is that expected?

Hi @joetannenbaum, does it trigger renders or is the callback function being invoked many times?

I implemented the hook based on https://react.dev/reference/react/useSyncExternalStore#subscribing-to-a-browser-api. I could try to extract the snapshot function from the component so it's using the same reference. Might be the issue.

@joetannenbaum Unfortunately I can't test the fix because I added it on mobile. Would you be able to check if my recent commit fixes the issue?

I can test the changes this friday.
