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

Major improvements to Issues #138, #139, and #140 with comprehensive
decoupled functionality approach:
## Issues Resolved
- Issue #138: Complete markdown parsing, directory creation, filename generation
- Issue #139: Full CLI integration, content aggregation, directory analysis,
end-to-end roundtrip testing, filename decoding system
- Issue #140: Fixed critical CLI parameter passing bug in roundtrip tests
## Key Features Added
- Comprehensive filename decoding system with special character restoration
- API version pattern handling (api_v2_1_reference.md → API v2.1: Reference)
- Smart title case with acronym recognition (API, SQL, HTTP, etc.)
- Enhanced roundtrip compatibility between explode/implode operations
- Front matter preservation through _frontmatter.yml files
- FilenameDecoder class for configurable batch processing
## Bug Fixes
- Fixed ImplodeOptions parameter passing in md_implode_command
- Corrected heading level preservation in roundtrip cycles
- Fixed README.md inclusion for roundtrip compatibility
- Enhanced pattern matching order to prevent conflicts
## Test Results
- All Issue #139 filename decoding tests: 18/18 passing ✅
- All Issue #140 roundtrip tests: 4/4 passing ✅
- Comprehensive test coverage for all new functionality
