feat: complete Issue #149 - Phase 2: Implement Explode-Implode Variants

Implement all three explode-implode variants with full CLI integration:

🔧 Variant Implementations:
- FlatVariant: Encapsulates existing flat structure behavior
- HierarchicalVariant: Numbered directory structures (01_, 02_, 03_)
- SemanticVariant: Content-based organization (intro, chapters, appendices)

🏭 Factory System:
- VariantFactory: Centralized variant creation and management
- Auto-detection algorithms with confidence scoring
- Content analysis for variant recommendation

🖥️ CLI Integration:
- Enhanced md-explode command with --variant parameter
- Enhanced md-implode command with auto-detection
- Improved error handling and user feedback

🧪 Comprehensive Testing:
- 22 unit tests covering all variant functionality
- Roundtrip validation ensuring perfect reversibility
- Performance testing with large documents
- Error handling and edge case coverage

📊 Key Features:
- Three distinct organization strategies
- Automatic variant detection from directory structures
- Full backward compatibility with existing behavior
- Extensible architecture for future variants
- Manifest-based reversibility
