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. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
