Contributions summary:Levi primarily focused on enhancements and refactoring within the Akka project, specifically related to the testkit and cluster sharding features. Their contributions include making the `TestProbe` a `RecipientRef` for typed actors, introspection support for typed `EntityRefs` to allow serialization, and introducing an `AbstractOnMessageBehavior` for Java DSL. Furthermore, they refactored the concurrency model in `AsyncDnsResolver` and added a `thenStop` method to `ReplyEffects`.
