Code Review

This pull request introduces Wear OS Navigation3 support by updating project dependencies and adding a sample implementation. The changes include defining serializable destinations and setting up a NavDisplay with a swipe-to-dismiss strategy. Feedback focuses on ensuring the rememberSwipeDismissableSceneStrategy correctly handles back navigation via an onDismiss lambda and recommending the use of a SaveableStateHolder decorator to preserve UI state across transitions.

The rememberSwipeDismissableSceneStrategy function requires an onDismiss lambda to handle the back navigation when a swipe gesture is completed. Without this, the swipe-to-dismiss gesture will not update the back stack.

Suggested change

	val strategy = rememberSwipeDismissableSceneStrategy<NavKey>()
	val strategy = rememberSwipeDismissableSceneStrategy<NavKey> {
	backStack.removeLast()
	}
