///! Comprehensive OSIRIS + OpenRPC Example
///!
///! This example demonstrates:
///! 1. Starting a Hero Supervisor with OpenRPC server
///! 2. Starting an OSIRIS runner
///! 3. Registering the runner with the supervisor
///! 4. Dispatching multiple OSIRIS jobs via OpenRPC
///! 5. Monitoring job execution
///! 6. Graceful shutdown
///!
///! Usage:
///! ```bash
///! cargo run --example osiris_openrpc
///! ```
