//! High-level pub/sub + request-reply over the agent-mesh transport.
//!
//! This commit lands the application-level message dispatch surface
//! ([`Inbox`], [`BusMessage`]). The high-level [`Bus`] type that
//! drives it lands in the next commit.
//!
//! What's already in place from prior commits:
//!
//! 1. **Topic namespacing** ([`Topic`]) — every pub/sub name is
//! scoped to the issuing user's fingerprint, so two unrelated
//! users on the same LAN can never collide.
//! 2. **Replay defense** ([`replay::NonceCache`] +
//! [`replay::SequenceTracker`]) — duplicate nonces and
//! out-of-order sequence numbers from a known peer are rejected.
