Handle Startup State

Reads the optional initialState string returned by connectToHostApp() and restores it before first render, so the app opens directly into the right view instead of always starting from defaults.

Requires @cognite/app-sdk's connectToHostApp() handshake already wired up. If auth isn't wired up yet, run the setup-flows-auth skill first.

What initialState actually is

initialState is a single opaque string, present on the object returned by connectToHostApp():

const { api, initialState } = await connectToHostApp();
