Kafka Support Improvements in Wolverine 6.13

This article details the Kafka support improvements in Wolverine 6.13, a framework for .NET. Key enhancements include fixing a bug that disabled real batch sending, resulting in up to 20x throughput improvement. A new commit-strategy overhaul introduces four modes: StoreThenAutoFlush (default), PerMessage, BatchCount, and BatchInterval, each suited for different traffic patterns. Additionally, in-flight-safe offset watermarks prevent message loss during out-of-order completion, and the DLQ path now commits specific TopicPartitionOffsets. These changes make Kafka integration more idiomatic and robust.
