-/// This trait allows the shared constructor in mod.rs to call version-specific 
-/// initialization while we incrementally migrate v1 async operations to use 
-/// the new event-driven interrupt pattern. Will be removed once the rework 
-/// is complete and both blocking/async modes use unified initialization.
