ExperimentalAppFunctionsFeature

Marks ADK's AppFunctions APIs as experimental: their shape and semantics may change in future releases without prior notice, as the underlying AppFunctions SDK is itself pre-release.

Opt in explicitly with @OptIn(ExperimentalAppFunctionsFeature::class) to use them. ADK declares androidx.appfunctions as compileOnly, so an app using these APIs adds that dependency itself, whether the functions come from its own package or another app's.
