+// Circle Worker Manager Example
+//
+// This example demonstrates how to use the service manager to dynamically launch
+// circle workers for new freezone residents. This is the primary use case requested
+// by the team.
+//
+// Usage:
+//
+// On macOS (uses launchctl):
+//   herodo examples/service_manager/circle_worker_manager.rhai
+//
+// On Linux (uses zinit - requires zinit to be running):
+//   First start zinit: zinit -s /tmp/zinit.sock init
+//   herodo examples/service_manager/circle_worker_manager.rhai
