a2a-agents 0.4.0

//! Core framework infrastructure for building A2A agents.
//!
//! This module provides the essential building blocks for creating A2A protocol agents:
//! - [`builder`] - Declarative agent builder with fluent API
//! - [`config`] - TOML-based configuration system
//! - [`runtime`] - Agent runtime and server management
//!
//! # Example
//!
//! ```rust,ignore
//! use a2a_agents::core::{AgentBuilder, AgentConfig};
//!
//! #[tokio::main]
//! async fn main() -> Result<(), Box<dyn std::error::Error>> {
//!     AgentBuilder::from_file("config.toml")?
//!         .with_handler(my_handler)
//!         .build_with_auto_storage()
//!         .await?
//!         .run()
//!         .await?;
//!     Ok(())
//! }
//! ```
