Kafka domain event publisher implementing IDomainEventPublisher, sibling to Svrnty.CQRS.Events.RabbitMQ. Uses Confluent.Kafka 2.6.1, targets net10.0 with C# 14. Features: - Configurable bootstrap servers, client id, idempotence, acks, retries - Security protocol + SASL config (Plaintext/SSL/SASL_SSL etc.) - Topic mapper (default lowercase event-type-name, custom func override) - IAsyncDisposable producer cleanup - Two registration overloads via AddKafkaDomainEvents Project added to solution. Builds with 0 warnings. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
