reckon_db_gateway_worker (reckon_db v1.2.7)

Gateway worker for reckon-db

This worker process acts as the gateway endpoint for a store. It registers with reckon-gater and handles incoming requests routed through the gateway API.

Multiple gateway workers can run per store for load balancing. Each worker registers independently with the gater's Ra-based worker registry.

The message format matches the ExESDB.GatewayWorker from the original Elixir implementation.
