/**
 * Calculates the MELD (Model for End-Stage Liver Disease) Score
 *
 * The MELD score is a validated scoring system used to assess the severity of
 * end-stage liver disease and predict short-term mortality. It is widely used
 * in surgical risk assessment and liver transplant allocation.
 *
 * Formula: MELD = 3.78 × ln(bilirubin) + 11.2 × ln(INR) + 9.57 × ln(creatinine) + 6.43
 *
 * @param input - Laboratory values and dialysis status
 * @returns MELD score result with risk assessment and recommendations
 * @throws {CalculatorError} If input validation fails
 *
 * @example
 * ```typescript
 * const result = calculateMELDScore({
 *   bilirubin: 2.5,
 *   creatinine: 1.8,
 *   inr: 1.6,
 *   dialysis: false
 * });
 * console.log(result.score); // 18
 * console.log(result.risk); // 'moderate'
 * ```
