RtSensorDataController spins up a background RtSensorDataWorker (queue, averaging, dense mat-vec mapping, ABGR packing) and an optional RtSensorInterpolationMatWorker (asynchronous recomputation of the dense mapping matrix when the sensor configuration, projectors or target surface change) and ties them together with a timer that paces the streaming.

Once started, the controller emits ready-to-upload per-vertex colour buffers; the GUI just connects newSensorColorsAvailable to its surface-colour slot.
