Remove async-trait dependency and use native Rust async fn in traits. Replace Arc<dyn Trait> with Arc<ConcreteType> throughout the codebase to enable monomorphization and eliminate dynamic dispatch overhead. Key changes: - Remove write-behind cache (no implementation existed) - Fix should_transcode static method call - Use ContactStorageAdapter directly instead of dyn AddressBookUseCase - Clean up unused trait imports across services and DI https://claude.ai/code/session_01EbAFEfyJNLRmJHmmYDX3Tt
