Navigation 3 + Koin: entryProvider is Any-typed and breaks typed SceneStrategy

[hmzgtl16]

When using Koin Navigation 3 integration, the provided koinEntryProvider() always returns:

(Any) -> NavEntry<Any>

This works as long as NavDisplay is inferred as NavDisplay.

However, when using a typed SceneStrategy, such as:

rememberSupportingPaneSceneStrategy<Route>()

NavDisplay becomes explicitly typed as NavDisplay, and the compiler then expects:

(Route) -> NavEntry<Route>

This causes a type mismatch, even though the setup works correctly at runtime.

Reproduction

@Composable
fun NavHost(
    backStack: NavBackStack<Route>,
    onBack: () -> Unit
) {
    val entryProvider = koinEntryProvider()
    val sceneStrategy = rememberSupportingPaneSceneStrategy<Route>()

    NavDisplay(
        backStack = backStack,
        onBack = onBack,
        sceneStrategy = sceneStrategy,
        entryProvider = entryProvider // ❌ type mismatch
    )
}

Compiler error:

Argument type mismatch: actual type is "Function1<Any, NavEntry<Any>>", but "Function1<Route, NavEntry<Route>>" was expected.

Important observation

If sceneStrategy is removed, the code compiles and works:

NavDisplay(
    backStack = backStack,
    onBack = onBack,
    entryProvider = entryProvider // ✅ compiles
)

This happens because NavDisplay is inferred as NavDisplay when no typed SceneStrategy is provided.
