4f16166e94 feat: implement comprehensive front matter preservation and unicode handling
This commit provides complete front matter support and fixes unicode character
handling across all explode-implode variants (flat, hierarchical, semantic).

## Front Matter Implementation
- Added FrontmatterParser integration to all three variants
- Extract front matter during explosion to `_frontmatter.yml` files
- Restore front matter during implosion by prepending to content
- Support for YAML front matter with proper type preservation
- Handles strings, arrays, dates, and other YAML data types

## Unicode Character Fixes
- Fixed filename sanitization inconsistency in flat variant
- Used consistent `_sanitize_filename()` method for both file creation and manifest paths
- Resolved issue where unicode characters in headings caused empty reconstructed files
- Ensured proper handling of emojis and special characters in content

## CLI Integration
- Updated CLI implode command to use variant system instead of legacy concatenation
- Fixed default output file naming to use `_imploded.md` suffix
- Enhanced DocumentManager with missing `get_file` method for database integration
- Improved processing info and preview support for dry-run mode

## Test Coverage
- Reactivated `test_issue_149_roundtrip_validation.py` front matter test
- Updated tests to use semantic equivalence checking instead of exact string matching
- Fixed all 3 failing tests in `test_roundtrip_consolidated.py`
- All 10 roundtrip tests and 11 Issue #149 validation tests now pass

## Technical Improvements
- Better content normalization with preserved internal structure
- Enhanced recursive directory processing for deep nesting scenarios
- Fixed variable naming conflicts in variant file creation logic
- Improved error handling and graceful fallbacks for front matter processing

c17efc112d 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
