feat: consumer name

[fearlessfei]

Used to identify the uniqueness of consumers.

Greptile Summary

This PR adds a Name() method to the kafkaQueue struct in the Kafka queue implementation. The method is a simple getter that returns the consumer name from the configuration (q.c.Name). This change enables consumers to be uniquely identified by name, which is essential for monitoring, debugging, and managing multiple queue instances in distributed systems.

The implementation fits into the existing codebase architecture by likely satisfying an interface contract from the go-zero framework's queue.MessageQueue interface. The kafkaQueue struct already contains a configuration field (q.c) with a Name property, so this change simply exposes that existing data through a standardized method. This is a common pattern in Go where structs implement interfaces by providing required methods.

The change integrates seamlessly with the existing queue management system, allowing developers to programmatically access queue names for logging, metrics collection, or administrative purposes. Since queue names are already being configured in the KqConf structure, this method provides a clean API to access that information without breaking encapsulation.

Confidence score: 5/5
