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

/**
 * @file Unused endpoint detector for backend optimization analysis
 * @description Single responsibility: Identify backend endpoints not utilized by frontend applications
 * 
 * This module implements reverse cross-reference analysis to identify backend endpoints
 * that have no corresponding frontend API calls. This analysis helps identify dead code,
 * over-engineered APIs, and maintenance overhead from unused functionality, enabling
 * backend optimization and reducing complexity in API surface area.
 * 
 * Design rationale:
 * - Reverse analysis identifies backend optimization opportunities
 * - Route normalization handles matching despite format variations
 * - Usage frequency analysis prioritizes cleanup efforts effectively
 * - Currently implemented as stub for future comprehensive analysis implementation
 */

/**
 * Detect unused backend endpoints using reverse cross-reference analysis (implementation pending)
 * 
 * Technical function: Cross-reference backend endpoints against frontend calls to identify unused APIs
 * 
 * Implementation rationale (planned):
 * - Route normalization will handle path parameter and format variations
 * - Method-specific matching will ensure comprehensive endpoint coverage analysis
 * - Fuzzy matching will accommodate slight route variations in frontend calls
 * - Age and complexity analysis will prioritize removal of older, complex unused endpoints
 * 
 * Analysis strategy (planned):
 * - Create lookup map of frontend calls by method and normalized route
 * - Iterate through backend endpoints to identify unmatched implementations
 * - Analyze endpoint complexity and maintenance overhead for prioritization
 * - Generate removal recommendations with impact and effort assessments
 * 
 * Unused endpoint patterns to identify:
 * - Legacy endpoints: Implemented but no longer called by current frontend
 * - Over-engineered APIs: More endpoints than needed for current functionality
 * - Test endpoints: Development/testing routes accidentally deployed to production
 * - Deprecated APIs: Old versions maintained but not actively used
 * 
 * Cleanup priority assessment:
 * - High: Complex unused endpoints with high maintenance overhead
 * - Medium: Simple unused endpoints with minimal dependencies
 * - Low: Recently created endpoints that may have future usage plans
 * - Exclude: Health checks, monitoring, and administrative endpoints
 * 
 * Removal impact considerations:
 * - Documentation references that need updating
 * - External API consumers (mobile apps, third-party integrations)
 * - Deployment pipeline dependencies
 * - Database migrations and cleanup requirements
 * 
 * @param {Array<Object>} backendEndpoints - Backend endpoints with method, route, file, complexity
 * @param {Array<Object>} frontendCalls - Frontend API calls with method, route, file, line
 * @returns {Array<Object>} Unused endpoint analysis results (currently empty - implementation pending)
 * @example
 *   const unused = detectUnusedEndpoints([
 *     { method: 'GET', route: '/api/legacy-users', file: 'legacy.js' },
 *     { method: 'GET', route: '/api/users', file: 'users.js' }
 *   ], [
 *     { method: 'GET', route: '/api/users', file: 'UserList.jsx', line: 10 }
 *   ]);
 *   // Should return: [{ method: 'GET', route: '/api/legacy-users', priority: 'HIGH', ... }]
