//! Demo: Evolution event bus receiving live agent telemetry.
//!
//! Creates an EvolutionBus, attaches it to a mock scenario, and prints
//! events as they arrive. This demonstrates the full pipeline:
//!
//!   Agent emit_event(AgentEvent) → EvolutionBridgeEmitter → EvolutionBus → subscriber
//!
//! Usage: cargo run --example evolution_bus_demo
