…orts Add StampFailureMetadata helper to DeadLetterQueueConstants that stamps exception-type, exception-message, exception-stack, and failed-at headers on envelopes before moving to DLQ. Applied consistently to SQS, GCP Pub/Sub, Azure Service Bus, NATS, Pulsar, RabbitMQ (InteropFriendly), BufferedReceiver, and DurableReceiver. Add UseEnhancedDeadLettering option for RabbitMQ that publishes to DLQ with metadata headers instead of native NACK. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
