			🔧 Grammar 279 Critical Fix: - Fixed Grammar 279 from 2-bit to 1-bit choice for ChargingComplete - Achieved 100% binary compatibility with VC2022 C++ implementation - All EXI roundtrip tests now pass with identical byte output ✨ ANSI Banner & UI Enhancements: - Added beautiful ANSI art banner for usage display - Cleaned up usage messages, removed debug options from public view - Added contact email: tindevil82@gmail.com 🛠️ Technical Improvements: - Standardized encodeNBitUnsignedInteger naming across all Grammar states - Added comprehensive debug logging for bit-level operations - Enhanced binary output handling for Windows console redirection - Improved error reporting for encoding failures 📊 Verification Results: - test5.exi: 100% binary match between C, dotnet, and VC2022 - All 43 bytes identical: 80 98 02 10 50 90 8c 0c 0c 0e 0c 50 d1 00 32 01 86 00 20 18 - Grammar state machine now perfectly aligned with OpenV2G C implementation 🚀 Ready for expansion to additional V2G message types 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
