Port Kafka queue tracing to the Spring and Spring Boot 2 modules. Add Spring Kafka bean post-processors, Boot 2 auto-configuration, and matching sample system-test coverage. Co-Authored-By: Claude <noreply@anthropic.com>
Document when to load queue-specific Cursor rules and summarize how Sentry Queues data is produced by the Java SDK Kafka instrumentation. Co-Authored-By: Claude <noreply@anthropic.com>

PR Stack (Queue Instrumentation)
📜 Description
Ports the Spring Boot 3 Kafka queue tracing stack changes to Spring Boot 2 as one PR.
This adds Spring Kafka support to the Spring 5 module, wires it into the Spring Boot 2 auto-configuration, and adds Boot 2 sample/system-test coverage for the regular, OTel agent, and OTel no-agent samples.
It also adds Cursor rules for queue tracing so future agent work has a high-level reference for how Sentry Queues data is produced by the Java SDK.
💡 Motivation and Context
The queue instrumentation stack added Kafka tracing for newer Spring Boot generations. Spring Boot 2 uses the Spring 5 module, so it needs the same Kafka producer/consumer bean post-processors and auto-configuration in the Boot 2 integration.
The new rules file documents when to load queue-specific guidance and summarizes the relationship between Sentry Queues, queue spans, Kafka instrumentation, and Spring Kafka auto-instrumentation.
