Struct TopicDescriptionHandle 

pub struct TopicDescriptionHandle { /* private fields */ }

Untypisiertes TopicDescription-Handle, das aus DomainParticipant::lookup_topicdescription / DomainParticipant::find_topic zurueckgegeben wird.

Die Spec-API liefert die abstrakte Base-Klasse, weil der Caller im Generalfall den Typ noch nicht kennt (z.B. nach Discovery). Wir packen Name + Type-Name + Participant in ein clone-bares Handle; der Caller kann get_type_name() lesen und sich dann per create_topic::<T> einen typed Handle holen.
