//! WarzonePhone Protocol — shared types, traits, and core logic.
//!
//! This crate defines the contracts between all other wzp-* crates.
//! It contains:
//! - Wire format types (MediaHeader, MediaPacket, SignalMessage)
//! - Codec, FEC, crypto, and transport trait definitions
//! - Adaptive quality controller
//! - Jitter buffer
//! - Session state machine
//!
//! Compatible with the Warzone messenger identity model:
//! - Identity = 32-byte seed → HKDF → Ed25519 (signing) + X25519 (encryption)
//! - Fingerprint = SHA-256(Ed25519 pub)[:16]
