feat: Complete Issue #6 - Generate Markdown Stub from Schema

Browse Source 
🎯 Core Implementation:
- StubGenerator class with intelligent heading hierarchy generation
- CLI command 'generate-stub' with comprehensive options (--output, --style, --title)
- Multiple placeholder styles: default, custom, detailed
- Full file I/O support and error handling

📊 Features Delivered:
- Template generation from JSON schemas with proper heading structure
- Intelligent section naming based on document hierarchy
- Round-trip validation: generated stubs validate against source schemas
- Integration with existing schema generation and validation workflow

🧪 Quality Assurance:
- 23 comprehensive tests covering all functionality
- Complete TDD8 methodology: RED-GREEN-REFACTOR cycle
- CLI integration tests and error handling validation
- 417/417 total tests passing - no regressions

🔄 Bidirectional Workflow Complete:
Schema Generation (✅ Issue #5) → Schema Validation (✅ Issue #7) → Stub Generation (✅ Issue #6)

This completes the critical template-driven document creation workflow essential
for arc42 architecture documentation system goals.

Usage Examples:
  markitect generate-stub blog_schema.json --output template.md
  markitect generate-stub schema.json --style detailed --title "My Document"

🎖️ Strategic Achievement: Template generation foundation complete and production-ready
