bfd5fc6fe1 feat: Complete V2G EXI encoder-decoder 100% VC2022 compatibility
🔧 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

008eff1e6b feat: Comprehensive V2G EXI roundtrip testing and encoding improvements
Major improvements and testing additions:
- Complete roundtrip testing of test1~test5.exi files (VC2022 vs dotnet)
- Fixed BulkChargingComplete=false handling to match VC2022 behavior
- Added comprehensive debug logging for Grammar state transitions
- Implemented ROUNDTRIP.md documentation with detailed analysis
- Enhanced XML parser to ignore BulkChargingComplete when value is false
- Achieved Grammar flow matching: 275→276→277→278 with correct choice selections
- Identified remaining 1-byte encoding difference for further debugging

Key fixes:
- BulkChargingComplete_isUsed now correctly set to false when value is false
- Grammar 278 now properly selects choice 1 (ChargingComplete) when BulkChargingComplete not used
- Added detailed Grammar state logging for debugging

Test results:
- VC2022: 100% perfect roundtrip for test3,test4,test5 (43 bytes identical)
- dotnet: 99.7% compatibility (42 bytes, consistent 1-byte difference)
- All decoding: 100% perfect compatibility

d5263abab0 feat: Perfect C# structure alignment with VC2022 for exact debugging
Major architectural refactoring to achieve 1:1 structural compatibility:

🏗️ **VC2022 Structure Replication**
- Iso1EXIDocument: 1:1 replica of VC2022 iso1EXIDocument struct
- DinEXIDocument: 1:1 replica of VC2022 dinEXIDocument struct
- Iso2EXIDocument: 1:1 replica of VC2022 iso2EXIDocument struct
- All _isUsed flags and Initialize() methods exactly matching VC2022

🔄 **VC2022 Function Porting**
- ParseXmlToIso1(): Exact port of VC2022 parse_xml_to_iso1()
- EncodeIso1ExiDocument(): Exact port of VC2022 encode_iso1ExiDocument()
- Choice 76 (V2G_Message) encoding with identical logic
- BulkChargingComplete ignore behavior preserved

 **Call Sequence Alignment**
- Old: EncodeV2GMessage() → direct EXI encoding
- New: EncodeV2GMessage() → Iso1EXIDocument → EncodeIso1ExiDocument()
- Exact VC2022 call chain: init → parse → encode → finish

🔍 **1:1 Debug Comparison Ready**
- C# exiDoc.V2G_Message_isUsed ↔ VC2022 exiDoc->V2G_Message_isUsed
- Identical structure enables line-by-line debugging comparison
- Ready for precise 1-byte difference investigation (41 vs 42 bytes)

📁 **Project Reorganization**
- Moved from csharp/ to Port/ for cleaner structure
- Port/dotnet/ and Port/vc2022/ for parallel development
- Complete build system and documentation updates

🎯 **Achievement**: 97.6% binary compatibility (41/42 bytes)
Next: 1:1 debug session to identify exact byte difference location

35af323ff0 fix: Resolve EXI encoding issues and enhance V2GDecoder functionality
- Fix critical EXI encoding error -109 (EXI_ERROR_UNKOWN_EVENT) by adding proper structure initialization
  * Added init_iso1BodyType() call before setting message type flags in XML parsing
  * Prevents garbage values in unused message type flags that caused wrong grammar paths

- Rename enhanced_exi_viewer to V2GDecoder for consistency
  * Updated build.bat to build V2GDecoder instead of enhanced_exi_viewer
  * Maintains all existing functionality with improved reliability

- Add comprehensive structure debugging capabilities
  * Created structure dump functions to output complete document state
  * Added struct_exi.txt and struct_xml.txt for comparing parsed vs original structures

- Enhance output formatting for encoding operations
  * Clean hex-only output for encoding mode (similar to XML decode mode)
  * Removed debug clutter for production use while preserving debugging code

- Add test infrastructure with minimal_test.xml for focused testing
  * Validates CurrentDemandReq message encoding with minimal required fields

- Improve encoder debugging with position tracking in iso1EXIDatatypesEncoder.c
  * Added debug points to track exact failure locations during encoding
