Previously, the app had a NavHost but didn't actually call navigate. NavHost's startDestination was read from external state (the currently selected nav item), which led to some undesirable behaviors. - NavHost itself was recomposed when selecting a nav item. - Pressing back always exited the app because you were always at the start destination. Now the NavHost has a stable startDestination, and nav item state is driven by the NavHostController's current destination. Selecting a nav item calls navigate, and the user always goes back through the startDestination before exiting the app.

Nit: since 2.8.1 is released, can we use that?

Consolidates all the navigation into one NavHost. A single NavigationSuiteScaffold is used to show top-level routes, with logic to hide some or all forms of navigation based on the current destination.
Fixes #96.
