fix fermi basis completion and expand localization coverage - Preserve independent fermion momenta when completing localization bases. - Add one-loop triple-pole and non-aligned two-loop convergence tests. - Strengthen analytic normalization and UV composition checks. - Enable cold-dense tennis-ball inspection with profile-dependence checks. - Document the independent two-loop reference in the run card.
