Peterino2 0c5383f518 Fix SDL3 parser critical issues and add comprehensive test plans 
## Critical Fixes Implemented

### 1. Memory Leak Resolution
- Fixed doc comment allocation in peekDocComment() to properly allocate memory
- Added cleanup for pending_doc_comment when skipping lines
- All tests now run with zero memory leaks (GPA verified)

### 2. Flag Definition Parsing (CRITICAL)
- Added skipWhitespace() helper to handle newlines before #define statements
- Flag structures now properly populated with all fields
- Before: empty structs with only padding
- After: all 7 flags present in GPUTextureUsageFlags

### 3. Invalid Identifier Generation (CRITICAL)
- Implemented "first underscore" naming rule
- Prevents enum values starting with numbers (e.g., 16bit, 2d)
- detectCommonPrefix() now only strips SDL_GPU_/SDL_ prefix
- enumValueToZig() splits on first underscore to preserve type prefix

### 4. Naming Convention Alignment
- Changed from "last underscore" to "first underscore" rule
- Type part: all lowercase (e.g., primitivetype)
- Value part: TitleCamelCase (e.g., Trianglelist)
- Result: primitivetypeTrianglelist (matches existing codebase)
- Added screaminToTitleCamel() helper for proper camelCase conversion

## Test Coverage

### New Tests Added
- patterns.zig: 3 new tests for flag scanning with whitespace
- naming.zig: 10 new comprehensive tests for naming conventions
- All 18 unit tests passing
- Integration test with SDL_gpu.h successful (169 declarations)

### Files Modified
1. **patterns.zig**
   - Added skipWhitespace() helper (lines 609-618)
   - Updated scanFlagTypedef() to skip whitespace before #define
   - Added 3 new flag scanning tests

2. **naming.zig**
   - Rewrote detectCommonPrefix() to only strip SDL prefix
   - Rewrote enumValueToZig() with first underscore rule
   - Added screaminToTitleCamel() helper
   - Added 10 comprehensive naming tests

3. **parser.zig**
   - Previous memory leak fixes intact
   - No changes needed for this iteration

## Documentation Added

1. **PARSER_FIX_PLAN.md** - Detailed implementation plan
2. **IMPLEMENTATION_COMPLETE.md** - Summary of fixes and results
3. **TEST_HARNESS_PLAN.md** - Original test harness design
4. **TEST_HARNESS_PLAN_V2.md** - Enhanced plan with mock generation

## Verification

✅ Parser generates valid Zig code (no compilation errors)
✅ All flag fields populated correctly
✅ No invalid identifiers (no numeric prefixes)
✅ Naming matches existing codebase conventions
✅ All 18 unit tests passing
✅ No memory leaks (GPA verified)
✅ Successfully parsed SDL_gpu.h (169 declarations)

## Next Steps (Planned)

- Implement mock_codegen.zig for C stub generation
- Create test_project/ with complete build system
- Add function call coverage tests
- Implement golden file regression testing
