Stranded-asset risk score + write-down API

Stranded-asset risk score (0-100, higher = riskier) plus canonical impairment write-down: writeDown = assetValue x strandingProbability x (1 - recoverableShare). Risk-score weights: carbonIntensityRisk .35, remainingLifeRisk .25, transitionPolicyExposure .20, lowRecoverability .20 (inverted). Returns risk score, risk bucket, A-F grade, the estimated write-down (absolute and %), and a driver breakdown. Answers 'is this a stranded asset', 'estimate transition-scenario impairment write-down', 'score carbon-intensity and policy exposure'.
