Implements the iteratively-reweighted least-squares loop: solve a weighted least-squares problem against the leadfield, update the per-source weights from the resulting row norms, prune rows whose weight has collapsed below tolerance, and iterate until the relative weight change drops below the user threshold or the iteration cap is hit. Active-source bookkeeping is maintained throughout so the final InvSourceEstimate carries only non-zero rows.
