feat: implement sophisticated layered theme system for md-render

Browse Source 
MAJOR FEATURES:
- **Layered Theme Architecture**: Combine themes across UI, document, and branding scopes
- **Advanced Theme Combinations**: Support complex themes like "dark,academic" or "light,github,corporate"
- **Legacy Compatibility**: Existing --template usage continues to work seamlessly
- **Enhanced CLI Validation**: Proper theme validation with helpful error messages

TECHNICAL IMPROVEMENTS:
- Replace DocumentManager with CleanDocumentManager throughout codebase
- Add ThemeType custom click parameter with comprehensive validation
- Implement parse_theme_string() and combine_theme_properties() functions
- Add _get_template_css() and _generate_layered_css() methods
- Support for UI themes (light/dark), document themes (basic/github/academic), and branding themes (corporate/startup)

THEME CAPABILITIES:
- **Single themes**: basic, github, dark, academic, light, corporate, startup
- **Layered themes**: dark,academic combines dark UI with academic typography
- **Complex combinations**: light,github,corporate for branded GitHub-style documents
- **Intelligent property merging**: Later themes override earlier theme properties

QUALITY ASSURANCE:
- All template system tests passing (12/12)
- Fixed import errors and missing dependencies
- Updated test expectations for new validation messages
- Comprehensive validation prevents unknown theme usage

Breaking Change: --template parameter renamed to --theme with enhanced functionality
