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 Files Added: - markitect/explode_variants/flat_variant.py - markitect/explode_variants/hierarchical_variant.py - markitect/explode_variants/semantic_variant.py - markitect/explode_variants/variant_factory.py - tests/test_issue_149_explode_implode_variants.py - tests/test_issue_149_roundtrip_validation.py - cost_notes/issue_149_cost_2025-10-12.md Files Modified: - markitect/explode_variants/__init__.py (updated exports) - markitect/plugins/builtin/markdown_commands.py (CLI integration) 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
