Changed globalstore to not be split

[TheJeran]

In #684 the variable state in useGlobalStore got duplicated during prod and was being passed as "Default" to the webGPU component.

This uses a method described here

https://www.prisma.io/docs/orm/more/troubleshooting/nextjs

Keeps useGlobalStore as a single global object. Analysis is working in prod.

I'm new to globals. But this may be something we want to implement in all stores. Will need to read up on it.

Code Review

This pull request refactors the Zustand store initialization in src/GlobalStates/GlobalStore.ts to use a global singleton (globalThis) to prevent duplication across Next.js code chunks. Feedback highlights a critical issue where using globalThis on the server side can cause state leakage between concurrent user requests during server-side rendering (SSR). A code suggestion is provided to restrict the global singleton to the client side and instantiate a fresh store on the server.

In Next.js (SSR), globalThis on the server is shared across all concurrent requests. Storing the Zustand store on globalThis on the server can lead to state leakage between different users/requests if the store is ever modified during server-side rendering.

To prevent this, you should only use the globalThis singleton on the client side (where typeof window !== 'undefined'), and create a fresh/isolated store instance on the server side.

Suggested change

	export const useGlobalStore =
	globalThis.__appStore ?? (globalThis.__appStore = createStore())
	export const useGlobalStore =
	typeof window !== 'undefined'
	? (globalThis.__appStore ?? (globalThis.__appStore = createStore()))
	: createStore()
