Comprehensive static code analysis toolkit for identifying technical debt, security vulnerabilities, performance issues, and code quality problems

/**
 * @file Difference type aggregation utility for duplication pattern classification
 * @description Single responsibility: Aggregate and categorize different types of differences between code blocks
 * 
 * This utility performs systematic aggregation of difference types identified during code
 * block comparison, providing quantitative analysis of variation patterns that help determine
 * whether detected similarities represent true duplication opportunities. The categorization
 * enables sophisticated analysis of refactoring potential and parameterization opportunities.
 * 
 * Design rationale:
 * - Categorical difference aggregation enables systematic duplication analysis
 * - Quantitative totals provide statistical foundation for similarity assessment
 * - Type-specific counting reveals patterns in code variation (variables vs literals vs structure)
 * - Comprehensive categorization supports advanced duplication classification algorithms
 * - Systematic aggregation ensures consistent difference pattern analysis
 * 
 * Difference categorization framework:
 * - Variable name differences: Indicates parameterizable variations in identifier usage
 * - String literal differences: Suggests configuration or data parameterization opportunities
 * - Numeric differences: Reveals mathematical or threshold parameterization potential
 * - Function call differences: Indicates behavioral variation that might be parameterizable
 * - Structural differences: Represents fundamental algorithmic or logic variations
