Water-stress risk score (WRI Aqueduct) API

Water-stress risk score (0-100, higher = riskier) in WRI Aqueduct style: canonical withdrawalRatio = withdrawal / availableSupply drives the main term (0 -> 0, >=0.8 'extremely high' -> 1). Risk-score weights: withdrawalRatioRisk .35, baselineWaterStress .25, droughtExposure .20, reuseEfficiencyWeakness .20 (inverted recyclingRate). Returns risk score, risk bucket, A-F grade, the withdrawal ratio, and a driver breakdown. Answers 'how water-stressed is this site', 'compute WRI withdrawal-to-supply ratio', 'score drought and reuse-efficiency risk'.
