feat(kits): split LogoutListener from AttributeListener

[denischilik]

Summary

• Introduces KitIntegration.LogoutListener as a separate contract from the deprecated AttributeListener.
• KitManagerImpl.logout() invokes logout() only on kits that implement LogoutListener.
• All embedded kits that previously implemented AttributeListener now explicitly implement LogoutListener as well.
• AttributeListenerTestKit implements both interfaces for instrumented tests.

PR Summary

Medium Risk
Behavior changes for logout forwarding: KitManagerImpl.logout() now calls logout() only on kits implementing the new KitIntegration.LogoutListener, so any third-party/sideloaded kit relying on AttributeListener.logout() must be updated or will stop receiving logout callbacks.

Overview
Introduces a dedicated logout contract for kits. KitIntegration.LogoutListener is added and the logout() method is removed from the deprecated AttributeListener.

KitManagerImpl.logout() is updated to invoke logout only for providers implementing LogoutListener, and embedded kits/tests that previously relied on AttributeListener are updated to also implement LogoutListener so they continue receiving logout callbacks.
