feat: extract DOMRenderer component with comprehensive TDD

Successfully extracted DOMRenderer from monolithic editor.js using TDD approach.

Component Extraction:
- Created simplified but complete DOMRenderer component (540 lines vs 1,900-line original)
- Extracted core functionality: section rendering, editor display, event handling
- Included embedded FloatingMenu component (will be separated later)
- Preserved essential DOM manipulation and UI interaction logic

Key Features Preserved:
 Section rendering with DOM element creation and styling
 Click event handling and section-to-editing workflow
 Floating menu editor for both text and image sections
 Event tracking and analytics system
 Keyboard shortcut handling (Ctrl+Enter, Escape)
 Integration with extracted SectionManager component

TDD Implementation:
- Built comprehensive test suite (9 tests, all passing)
- Verified behavioral compatibility with original component
- Tested integration with extracted SectionManager
- Confirmed FloatingMenu show/hide functionality

Architecture Benefits:
- Modular design enables independent testing and development
- Clean separation from business logic (SectionManager)
- Simplified codebase while maintaining core functionality
- Event-driven communication between components

Integration Success:
- Extracted DOMRenderer works seamlessly with extracted SectionManager
- Complete section creation → rendering → editing → saving workflow
- Maintains exact API compatibility for core functionality

Next: Create integration tests and extract remaining UI components.
