public class TransactionalDmxInterceptor
extends Object

CDI interceptor that backs TransactionalResult and TransactionalTry.

Activates on any method annotated with either TransactionalResult or TransactionalTry (both carry the shared DmxTransactionalBinding meta-interceptor-binding, per CDI §2.7.1.1). For each intercepted method the interceptor:

1. Resolves the Transactional.TxType from the annotation (default REQUIRED).
2. Applies the corresponding JTA propagation semantics via TxExecutor.
3. Rolls back (or marks rollback-only) if the returned Result is error or Try is failure.
4. Commits on success; rolls back and re-throws on any unchecked exception.

This interceptor is registered automatically when the fun-quarkus-deployment module is on the build classpath. No manual @EnableInterceptors or beans.xml registration is required in a standard Quarkus application.
