 In RabbitMQ, the default exchange (sometimes referred to as the default direct exchange) is a pre-declared, nameless direct exchange with a special behavior:

 - When you publish a message to the default exchange (exchange name = `""`) with a routing key set to the queue name, the message is delivered directly to that queue — no explicit binding is needed.

-channel.basic_publish(

+## Connection Resiliency
+
+The `RabbitMqChannelManager` provides enhanced connection resilience:
+
+- **Continuous Retry**: Unlike the previous 3-attempt limit, the connection now retries indefinitely in the background
+- **Automatic Recovery**: Integrates with RabbitMQ's built-in automatic recovery features
+- **Connection Monitoring**: Monitors connection shutdown events and triggers reconnection
+- **Health Integration**: The health check provides visibility into connection retry status
+- **Thread-Safe Operations**: All channel operations are properly synchronized
