//! An in-process loopback transport for hardware-free testing and examples.
//!
//! [`LoopbackTransport`] implements the core [`Transport`](pamoja_core::Transport)
//! trait against a shared in-memory [`LoopbackBroker`] instead of a network, so
//! examples, the simulators, and the cross-language conformance scenarios can
//! exercise the full publish/subscribe path with no broker process and no
//! hardware. Topic filters follow MQTT semantics, including the `+` single-level
//! and `#` multi-level wildcards.
//!
//! Clone one broker into every transport that should share a namespace: a publish
//! on any transport is delivered to every transport whose subscriptions match.
//!
//! [`Faulty`] decorates any transport to inject send failures, so degraded-link
//! behavior such as store-and-forward retry can be tested deterministically.
