Description

We think the create_topic should fail when it is called multiple times with the same topic_name. The spec is not concrete at it, I see that for example RTI Connext DDS doesn't allow this (see https://community.rti.com/rti-doc/500/ndds.5.0.0/doc/html/api_cpp/classDDSDomainParticipant.html#a7f249829f7ee94d1461d371800398a21), did report an issue on the DDS spec for this

Research direction

The issue identifies create_topic and the repeated topic_name case, but names no source file, test, or entry point. First trace the create_topic implementation and existing tests, then establish the intended DDS behavior before determining what a passing test should require.
