Encapsulates the heavy-weight GeometryInfo::scdc (geodesic distance Dijkstra) and Interpolation::createInterpolationMat (distance-based sparse weight build) calls. It supports two VisualizationType modes: InterpolationBased uses the smooth distance kernel, AnnotationBased uses a per-parcel uniform colouring derived from the FreeSurfer annotation so the cortex lights up parcel-by-parcel.

When recomputation finishes the new matrix is emitted to the data worker via a queued connection so no main-thread stall is visible to the user.
