//! Adapters for the A2A protocol
//!
//! This module provides concrete implementations of the port interfaces,
//! organized by concern:
//!
//! - `transport`: Protocol-specific implementations (HTTP, WebSocket)
//! - `business`: Business logic implementations  
//! - `storage`: Data persistence implementations
//! - `auth`: Authentication and authorization implementations
//! - `error`: Error types for all adapters
