//! Core types and protocol models for stdio_bus
//!
//! This crate provides the fundamental types used across all stdio_bus components:
//! - Error types with canonical error codes
//! - Bus state machine
//! - JSON-RPC message types
//! - Statistics and configuration types
//! - Backend trait for implementations
