Net-zero alignment score API

Net-zero alignment score (0-100, higher = better) combining a canonical decarbonization-pace ratio with a rubric: requiredAnnualReductionRate = 1 / (targetYear - currentYear), alignmentRatio = plannedAnnualReductionRate / requiredAnnualReductionRate (capped 2x). Score weights: reductionPaceAlignment .40 (from ratio), scope3Coverage .20, sbtiValidation .20, offsetReliance .20 (inverted). Returns score, rating, A-F grade, required vs planned rate, the alignment ratio, emissions reduced to date, and a breakdown. Answers 'is this firm on a net-zero path', 'compare planned vs required decarbonization pace', 'score SBTi-validated net-zero alignment'.
