StcLoadingWorker pulls the LH and RH .stc files from disk in a background thread, parses them into an INVLIB::InvSourceEstimate per hemisphere and builds the sparse vertex-to-source interpolation matrix using GeometryInfo::scdc / Interpolation::createInterpolationMat with a configurable geodesic cancel distance.

On completion the controller signals the GUI to attach the data to the cortical surfaces, after which scrubbing and playback are served by SourceEstimateOverlay without any further I/O.
