Implements per-label slicing of the vertex index list, the four aggregation kernels (simple mean, sign-flipped mean, PCA-flip via Eigen's SVD, and absolute-max), and the computeSignFlip helper that derives the per-vertex ±1 alignment from the first singular vector of the label's data block — the same recipe used by mne-python so that downstream ROI averages stay numerically comparable across the two stacks.
