/**
 * Data Validation Service
 *
 * Comprehensive validation service ensuring data integrity and structure
 * compliance for energy flow datasets. Performs multi-level validation
 * including structure, content, and value range verification.
 *
 * Validation Levels:
 * 1. Structure Validation - Array format and basic structure checks
 * 2. Content Validation - Required sectors and breakdown verification
 * 3. Type Validation - Ensures proper data types for all values
 * 4. Range Validation - Warns about unusual values or potential errors
 * 5. Duplicate Detection - Prevents duplicate years in dataset
 *
 * Error Handling:
 * Throws DataValidationError with detailed context for failed validations,
 * including field names, indices, and descriptive error messages.
 * Emits validation events for service coordination and monitoring.
 *
 * Required Data Structure:
 * Each data point must contain all major fuel types (solar, nuclear, hydro,
 * wind, geothermal, gas, coal, biomass, petroleum) with consumption
 * breakdowns across sectors (electricity, residential, agriculture,
 * industrial, transportation).
 *
 * Provides comprehensive validation for energy flow datasets with
 * multi-level checks ensuring data integrity, proper structure,
 * and content completeness. Maintains strict validation rules
 * to prevent downstream calculation errors.
