SearchSpaceGroup: drop the log10(chi2_ref) widening of the point-group chi^2-ratio bound and tighten max_merge_chi2_ratio 2.0 -> 1.85. The variance-floor fix removed the error-model miscalibration the widening compensated for, so the widening now only let a partial merohedral twin through (Ins_H_2 R3->R32 twin 2-fold: ratio 2.01). Every genuine high symmetry across the rotation-test battery stays within ~1.7x (worst real case Thau P41212 at 1.71), so 1.85 keeps R3 in its true lower symmetry. TwinningAnalysis: make the <I^2>/<I>^2 second moment robust - skip noise-only shells (<I/sigma> < 1) and reject Wilson outliers (E^2 > 8) with one shell-mean re-iteration, so a single strong reflection in a collapsed-mean shell no longer dominates the moment. Add MerohedralTwinningPossible: in a holohedral Laue class (4/mmm, 6/mmm, m-3m, rhombohedral -3m) no twin law exists, so a low <|L|> there is a statistical artefact and is no longer flagged as twinning.
