Economic Order Quantity (EOQ) API

Compute Economic Order Quantity (EOQ = √(2·D·S / H)) with optimal orders/year, cycle length, and total annual ordering + holding cost; accepts holding cost per unit or unitCost × holdingRate. Deterministic inventory optimization. Answers 'what is my optimal order quantity','EOQ for this demand and holding cost'.
