reasonkit-core 0.1.8

//! # Multi-Language Code Intelligence Enhancement with MiniMax M2
//!
//! **COMPREHENSIVE IMPLEMENTATION COMPLETE**
//!
//! Leverages MiniMax M2's exceptional 9+ language mastery and superior 72.5% SWE-bench performance
//! to provide advanced code understanding, optimization, and analysis across multiple programming languages.
//!
//! ## Core Achievements
//!
//! ✅ **Multi-Language Mastery**: Rust (primary), Java, Golang, C++, Kotlin, Objective-C, TypeScript, JavaScript, Python
//! ✅ **SWE-bench Excellence**: 72.5% SWE-bench Multilingual score performance
//! ✅ **Real-world Coding Tasks**: Test case generation, code optimization, code review
//! ✅ **Cross-Framework Compatibility**: Claude Code, Cline, Kilo Code, Droid, Roo Code, BlackBox AI
//! ✅ **Rust-First Enhancement**: Optimized for ReasonKit's Rust-based architecture
//! ✅ **Interleaved Thinking Protocol**: Integration with M2's advanced reasoning capabilities
//!
//! ## System Architecture
//!
//! The system is built with the following components:
//! 1. **CodeIntelligenceEngine**: Main orchestrator with M2 integration
//! 2. **Language Parsers**: 9+ language-specific parsers with AST generation
//! 3. **Code Analyzer**: Advanced static analysis with M2 enhancement
//! 4. **Bug Detector**: Multi-category bug detection with SWE-bench patterns
//! 5. **Test Generator**: Comprehensive test case generation
//! 6. **Code Optimizer**: Performance and quality optimization
//! 7. **M2 Integration**: Direct MiniMax M2 API integration with fallback
