mir-backend-jvm-micronaut

Make It Right (Micronaut module). Micronaut + Micronaut Data + Micronaut Security + Netty HTTP server reliability footguns specific to this framework stack. Covers: compile-time DI and AOT (no runtime reflection — missing bean is a compile error, not a runtime NPE), bean scope pitfalls (@Singleton default, don't hold request state), blocking the Netty event loop (use @ExecuteOn or reactive types), Micronaut Data repository transaction scoping, reactive types (RxJava / Reactor / Kotlin coroutines) and not blocking the event loop inside them, native-image / GraalVM considerations at the Micronaut layer, and compile-time AOP interceptor limitations. Always loads TOGETHER WITH mir-backend (the gates) and mir-backend-jvm (JVM runtime concerns: thread pools, virtual threads, GC, container heap, cold start, JMM visibility, ThreadLocal hygiene); this module only adds Micronaut library mechanics. TRIGGER only when the JVM backend stack is Micronaut — building, reviewing, or debugging a Micronaut controller, service, repository, filter, or security rule. SKIP for Spring Boot, Quarkus, Vert.x standalone, or any non-Micronaut JVM framework (those get their own mir-backend-jvm-<framework> module), and for non-JVM runtimes.
