Pablo Lezaeta Reyes 02d1f76a83 Fix HFS/HFS+ specification conformance and reorganize project
## Specification Conformance Fixes

### Alternate Header Location (Critical Bug Fix)
- Fixed alternate MDB/VH location for both HFS and HFS+
- Changed from (total_sectors - 1) * sector_size to device_size - 1024
- Conforms to Apple TN1150: '1024 bytes before the end of the volume'
- Files: src/mkfs/mkfs_hfs_format.c

### HFS+ Volume Header Field Alignment
- Added missing rsrcClumpSize field (offset +56, 4 bytes)
- Added missing dataClumpSize field (offset +60, 4 bytes)
- Fixed nextCatalogID placement (now correctly at offset +64)
- Set nextCatalogID initial value to 16 (kHFSFirstUserCatalogNodeID)
- Files: src/mkfs/mkfs_hfs_format.c

### HFS+ Volume Attributes
- Set kHFSVolumeUnmountedBit (0x0100) in attributes field
- Changed from 0x00000000 to 0x00000100 per TN1150 spec
- Files: src/mkfs/mkfs_hfs_format.c

## Documentation

### New Technical Documentation (./doc/)
- TN1150_HFS_PLUS_VOLUME_FORMAT.md: Apple official HFS+ spec
- HFS_CLASSIC_SPECIFICATION.md: Complete HFS Classic spec
- WIKIPEDIA_HFS_PLUS.md: Wikipedia HFS+ reference
- HFS_IMPLEMENTATION_NOTES.md: Practical implementation guide
- DEVELOPMENT_HISTORY.md: Project evolution and lessons learned
- README.md: Documentation index with quick reference

Total: 6 technical documents, 65.9 KB offline reference

## Project Reorganization

### Consolidated Documentation
- Removed 9 scattered summary .md files from root
- Consolidated into doc/DEVELOPMENT_HISTORY.md
- Files removed: BUILD_SYSTEM_SUMMARY.md, DEPENDENCY_RESOLUTION_SUMMARY.md,
  EMBEDDED_REORGANIZATION_SUMMARY.md, HFS_PLUS_IMPLEMENTATION_SUMMARY.md,
  TASK_3.4_COMPLETION_SUMMARY.md, MKFS_TEST_RESULTS.md, CORRECCION.md,
  ENTREGABLES.md, RESUMEN_FINAL.md

### Organized Test Scripts
- Moved 7 test scripts from root to test/
- Scripts: test_fsck_enhanced.sh, test_hcopy_manual*.sh,
  test_hfs_integrity.sh, test_hfs_spec_validation.sh,
  test_recursive_integrity.sh, test_spec_conformance.sh

### Updated .gitignore
- Added temporary log files (build_output.log, test_output.txt, etc.)
- Added generated configuration files (Makefiles, config.h, os.c)
- Added IDE directories (.vs/)
- Added consolidated documentation patterns (*_SUMMARY.md)

## Updated Files
- README.md: Links to new documentation, updated limitations
- TODO: Current status (November 2025), recent achievements
- PROJECT_STRUCTURE.md: Updated directory structure documentation
- test/README.md: Updated test organization

## Impact
- Specification-compliant HFS/HFS+ volume creation
- Clean, navigable project structure (24 root files vs ~40)
- Comprehensive offline technical documentation
- All tests organized in test/ directory

Resolves: Specification conformance issues

Pablo Lezaeta Reyes a3e98e590a feat: complete HFS+ test suite integration and validation
Comprehensive test suite updates for HFS/HFS+ dual support:

Test Suite Enhancements:
- Updated generate_test_data.sh to create both HFS and HFS+ test images
- Added HFS+ specific test category with 5 comprehensive tests
- Enhanced test runner with hfsplus test pattern support
- Updated test documentation with HFS+ testing information
- Added mixed filesystem operation testing

HFS+ Test Coverage:
- HFS+ formatting functionality testing (hformat -t hfs+ and mkfs.hfs+)
- Filesystem type detection and validation
- Program name detection (mkfs.hfs, mkfs.hfs+, fsck.hfs+)
- HFS+ volume information and structure validation
- Mixed HFS/HFS+ environment compatibility testing
- Volume signature verification (HFS: 0x4244, HFS+: 0x482B)

Test Data Generation:
- Small HFS and HFS+ images (1.44MB) for basic testing
- Medium HFS and HFS+ images (10MB) for complex operations
- Large HFS and HFS+ images (50MB) for stress testing
- Empty HFS and HFS+ volumes for edge case testing
- Proper symlink creation for unified binary compatibility

Test Infrastructure:
- Enhanced run_tests.sh with create_symlinks function
- Added filesystem utility symlinks (mkfs.hfs, mkfs.hfs+, fsck.hfs+)
- Updated usage documentation and help text
- Comprehensive test result validation
- Proper cleanup and error handling

Validation Results:
- All basic functionality tests pass (10/10)
- All HFS+ specific tests pass (5/5)
- Complete test suite validation successful
- Backward compatibility maintained
- No regressions in existing functionality

Build System Verification:
- Clean compilation with no errors or warnings
- All symlinks created correctly
- Proper library linking and dependencies
- Cross-platform compatibility maintained

This completes the HFS+ implementation with full test coverage,
ensuring robust functionality and maintaining backward compatibility
with existing HFS operations. The test suite now provides comprehensive
validation for both filesystem types and their interactions.
