Module command 

Command / Reply – Request-Style Commands and Responses (spec section 15)

Commands implement RPC semantics: a client sends a Command (carrying a correlation_id), the server processes it and returns a Reply (carrying the same correlation_id).

Flow

Client                         Server
  |                               |
  |-- Command { corr_id=42 } --->|
  |                               |  (process command)
  |<-- Reply { corr_id=42 } -----|
  |                               |

Supports idempotency (via idempotency_key) and timeout control (via timeout_ms).
