Major template system overhaul: 12+ professional templates and custom builder

✨ Features Added:
- 12 professional templates: Modern, Classic, Minimalist, Developer, Academic, Corporate, Startup, Gaming, Security, AI/ML, Mobile, Open Source
- Visual custom template builder with drag-and-drop interface
- Template management system with save/load functionality
- Enhanced repository analyzer with advanced feature detection
- Professional README generation with industry-specific content

🔧 Improvements:
- Enhanced all existing templates with comprehensive sections
- Added template preview with GitHub-style syntax highlighting
- Integrated template builder into main GUI interface
- Improved template selection with descriptions and management
- Added performance metrics and architectural analysis

📁 Files Changed:
- src/templates/readme_templates.py: 6 new templates + enhanced existing ones
- src/template_builder.py: Complete visual template builder (617 lines)
- src/gui.py: Template management integration and UI improvements
- src/analyzers/repository_analyzer.py: Enhanced feature detection

🧪 Tested:
- All 12 templates generating successfully
- Template builder fully functional
- Import issues resolved
- GUI integration complete
