docs: Figure out what behavior we want for isGPUSupported for SSR

const adapter = await navigator.gpu?.requestAdapter();
adapter?.requestDevice().then((device) => device.destroy());

export const isGPUSupported = !!adapter;

This code returns false if the navigator does not have the gpu field at all (for Node >20) but for Node<=20 it will throw an error since navigator is not a thing there. Maybe we should handle this case better to avoid confusion in the future.

Update:
What does this even do?

adapter?.requestDevice().then((device) => device.destroy());

Start by locating the TypeScript definition of isGPUSupported and inspect how SSR and Node environments reach it. Compare the navigator behavior described for Node <=20 and Node >20, and clarify the purpose of the requestAdapter/requestDevice sequence. Done means the supported SSR behavior and the intended handling of missing navigator.gpu are explicitly decided.
