/// Working example demonstrating Mycelium message routing between two nodes
///
/// This example proves that Hero Supervisor Mycelium integration works correctly
/// for distributed deployments by setting up two separate Mycelium nodes and
/// testing end-to-end message routing.
///
/// Key features:
/// - Starts two Mycelium nodes with proper port configuration
/// - Tests message push/pop functionality between nodes
/// - Starts Hero Supervisor on supervisor node
/// - Sends JSON-RPC messages from client node to supervisor
/// - Verifies complete end-to-end communication

//! # Hero Supervisor Client Demo (Limited)
//!
//! ⚠️ **Note**: This example has limitations due to Mycelium local loopback routing issues.
//! For a working example, use `mycelium_two_node_test.rs` instead.
//!
//! This example demonstrates SupervisorClient usage but is affected by Mycelium's
//! inability to route messages properly when both client and supervisor run on the same node.
//!
//! For production use, deploy client and supervisor on separate Mycelium nodes.
//!
//! To run this example:
//! ```bash
//! cd /Users/timurgordon/code/git.ourworld.tf/herocode/home/examples
//! cargo run --example supervisor_client_demo
//! ```
