//! Agent-to-Agent (A2A) protocol implementation with JSON-RPC, REST, and gRPC bindings.
//!
//! ## Features
//!
//! - `client` — HTTP client for JSON-RPC and REST (reqwest)
//! - `server` — HTTP server for JSON-RPC and REST (hyper)
//! - `native` — Both client and server (default)
//! - `grpc` — gRPC types (prost + tonic)
//! - `grpc-client` — gRPC client transport
//! - `grpc-server` — gRPC server service
//! - `full` — Everything
