Adds consumeActions for the event generator: scaffolds the handler file + test, the Payload event-task that completes the production-bus loop, modifies the consumer feature's symbols (// <gen:event-handler-symbols>), both binders (// <gen:event-handlers>), and the cms re-export (// <gen:job-tasks>). The bind block wraps the handler in span+capture, binds it into the per-feature container, and subscribes it on the bus.
