FEAT: Complete JsonMetaDataParser Enhancement + Inline Attribute Integration v5.2.0

Major architectural completion with comprehensive enhancements:

## JsonMetaDataParser Enhancement (296 lines improved)
- Enhanced inline attribute parsing with full type casting support
- Advanced cross-file reference resolution for complex package hierarchies
- Array-only metadata format support for streamlined definitions
- Improved error handling with context preservation and better debugging
- Package overlay capabilities for metadata augmentation patterns

## Unified Inline Attribute Support
- Integrated inline attribute support into FileMetaDataParser (63 new lines)
- XML and JSON parsers now share consistent inline attribute handling
- Unified API for @ prefixed JSON and non-prefixed XML inline attributes
- Complete type casting: Boolean, Integer, Double, String conversions

## Test Data Modernization
- All test metadata files updated to v5.2.0+ inline attribute standards
- Modernized format across codegen, maven-plugin, and metadata modules
- Consistent @ prefix usage for JSON inline attributes throughout
- All test resources now follow current architectural patterns

## Vehicle Test Suite - 100% Operational
- All 6/6 Vehicle domain tests now passing successfully
- Complete cross-file reference resolution working
- Full package inheritance, overlay patterns, and relative references
- Comprehensive coverage of all metadata format capabilities

## Additional Improvements
- Enhanced SimpleLoader with refined error handling
- Updated CoreMetaDataTypeProvider and CoreMetaDataContextProvider
- Improved XMLMetaDataParser inline attribute integration
- New test interface metadata file for enhanced code generation testing

## System Status
- ✅ Complete inline attribute support across all formats
- ✅ 100% Vehicle test suite operational
- ✅ Full cross-file reference resolution
- ✅ Unified XML/JSON parsing architecture
- ✅ Modern test data format compliance
