//! Wire protocol types and codec for the Iggy binary protocol.
//!
//! This crate is the single source of truth for the binary wire format
//! shared between the Iggy server and SDK. It is a pure codec - no I/O,
//! no async, no runtime dependencies.
//!
//! # Design
//!
//! Protocol types are independent from domain types.
//! Conversion between wire types and domain types happens at the boundary
//! (SDK client impls, server handlers).
//!
//! # Wire frame format
//!
//! **Request** (client -> server):
//! ```text
//! [length:4 bytes, u32 LE][code:4 bytes, u32 LE][payload:N bytes]
//! ```
//!
//! **Response** (server -> client):
//! ```text
//! [status:4 bytes, u32 LE][length:4 bytes, u32 LE][payload:N bytes]
//! ```
//!
//! All multi-byte integers are little-endian. Strings are length-prefixed
//! (u8 length for names, u32 length for longer strings).
