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

/**
 * @file Static bug recommendation generator for actionable fix guidance
 * @description Single responsibility: Generate prioritized, actionable recommendations for static bug resolution
 * 
 * This generator transforms static bug detection results into practical, prioritized action
 * items that development teams can implement to improve code quality. It provides context-aware
 * recommendations that consider bug severity, fix complexity, and business impact to guide
 * systematic code quality improvement efforts.
 * 
 * Design rationale:
 * - Priority-based recommendations enable teams to focus on highest-impact bug fixes
 * - Context-aware guidance provides practical implementation steps beyond generic advice
 * - Effort estimation helps teams plan bug fixing sprints and allocate resources effectively
 * - Category-specific recommendations provide targeted guidance for different bug types
 * - Actionable descriptions enable immediate implementation without additional research
 * 
 * Recommendation framework:
 * - Logic errors: Code flow analysis, conditional logic fixes, variable scope corrections
 * - Type issues: Type annotations, validation improvements, casting corrections
 * - Security vulnerabilities: Input validation, authentication fixes, authorization improvements
 * - Performance issues: Algorithm optimization, memory usage improvements, I/O efficiency
 * - Maintainability: Code organization, documentation, naming convention improvements
