back() and canGoBack() don't work after reloading the page on web

I didn't open an issue for this as I'm sure you guys are aware and working on it in v3.

I noticed that the store behind useRouter() is not persistent and doesn't work after a page reload.

For now I have worked around it by using window.navigation.back() and window.navigation.canGoBack when the platform is web.

On the web, window.navigation is an experimental feature and is not supported by all browsers. window.location.origin is the way to identify reloads. But when Expo Router loads nested routes, some internal redirects occur and origin is set.

I think Expo Router should identify the first route load, using window.navigation when available with fallback to origin and making it available via hook.
