/**
 * TypedMessageRetryReason — Typed enum for WhatsApp's retry reason codes
 *
 * Based on protocol research from whatsapp-rust and Baileys source.
 * These codes appear in message retry events when encryption fails.
 *
 * Common scenarios:
 * - SignalErrorBadMac (7) — Most common, indicates encryption session mismatch
 * - SignalErrorNoSession (5) — Peer hasn't established session yet
 * - SignalErrorInvalidKeyId (3) — Peer's prekey rotated
 * - MessageExpired (8) — Message too old to decrypt
