Add SentryKafkaProducerWrapper that overrides doSend to create queue.publish spans for all KafkaTemplate send operations. Injects sentry-trace, baggage, and sentry-task-enqueued-time headers for distributed tracing and receive latency calculation. Add SentryKafkaProducerBeanPostProcessor to automatically wrap KafkaTemplate beans. Co-Authored-By: Claude <noreply@anthropic.com>

…oducerInterceptor Replace the KafkaTemplate subclass approach with a Kafka-native ProducerInterceptor. The BeanPostProcessor now sets the interceptor on the existing KafkaTemplate instead of replacing the bean, which preserves any custom configuration on the template. Existing customer interceptors are composed using Spring's CompositeProducerInterceptor. If reflection fails to read the existing interceptor, a warning is logged.

TransactionContext constructor requires ScopesAdapter.getOptions() to be non-null for thread checker access. Add initForTest/close to ensure Sentry is properly initialized during tests. Co-Authored-By: Claude <noreply@anthropic.com>

Do we want to have any info on the fact, that header injection failed? A log for example?

Do we want to remove the full baggageHeader here? Would that not potentially remove baggage information from other instrumentation libraries? Ok with it if its intentional, just raising the point

we should take pre-existing baggage header(s) and feed it into the generated one
