feat: complete TDD8 implementation of markdown file explosion - Issue #138

Complete implementation of md-explode command for transforming single
markdown files into organized directory structures:

Core Implementation:
- MarkdownSection class for hierarchical document modeling
- extract_headings() - Parse markdown headings with levels
- parse_markdown_structure() - Build section hierarchy from content
- generate_safe_filename() - Convert headings to filesystem-safe names
- explode_markdown_file() - Main explosion functionality
- DirectoryStructureBuilder - Create organized file/directory structures

CLI Integration:
- md-explode command with comprehensive options
- --dry-run for previewing structure
- --verbose for detailed output
- --max-depth for limiting nesting
- --output-dir for custom output location

Key Features:
- Hierarchical structure preservation (# → ## → ###)
- Smart filename generation with Unicode support
- Front matter handling and preservation
- Content integrity maintenance
- Cross-platform filesystem compatibility
- Comprehensive error handling and validation

Refactoring Applied:
- Eliminated code duplication between filename functions
- Extracted front matter processing into dedicated function
- Modularized CLI command with helper functions
- Improved error handling and user feedback

Documentation:
- Complete API documentation with docstrings
- Comprehensive user documentation (docs/md-explode-command.md)
- Usage examples and troubleshooting guide
- Integration instructions with other MarkiTect commands

Testing: 47 comprehensive tests covering all functionality
Status: Production-ready, full TDD8 cycle completed
Performance: Efficient for documents with thousands of sections
