DataLoader is a thin facade over FSLIB and MNELIB readers that turns raw files (FsSurface, FsAnnotation, MNESourceSpaces, MNEBemSurface, FIFF digitizer / sensor blocks) into the in-memory objects that BrainTreeModel and the renderable/ layer expect. It exists so GUI code can populate the 3-D scene without knowing the FreeSurfer / MNE file-format conventions (subject directory layout, hemisphere suffixes, surface-RAS vs head coordinate frames, ...).

All methods are stateless and may be called from worker threads; they return shared pointers to the produced data structures and do not touch the Qt RHI or any GUI state.
