evoq_responder behaviour (evoq v1.14.1)

Responder behaviour for evoq.

Responders receive hopes (via mesh or hecate:// API), dispatch commands to the local aggregate, and return feedback containing the post-event aggregate state. This enables session-level consistency for RPC.

Naming convention: {command}_responder_v1
