feat: implement advanced image editing with drop zone and staging workflow
Completely redesigned image editing experience with professional workflow: ## 🎨 New Drop Zone Interface - **Drag & Drop Support**: Users can drag image files directly onto preview area - **Visual Feedback**: Border changes to green on dragover, overlay shows drop instruction - **Click to Select**: Alternative file selection by clicking the preview area - **File Type Validation**: Supports JPG, PNG, GIF, WebP with proper validation ## 📝 Staging System (Non-Destructive Editing) - **No Immediate Changes**: Image replacement and alt text edits are staged, not applied immediately - **Change Tracking**: Visual indicator shows when user has unsaved changes - **Preview Updates**: Users see staged changes in real-time preview without affecting document - **Staging State**: Maintains separate staged vs. current state for both image source and alt text ## 🎯 Enhanced Button Workflow - **Accept**: Applies all staged changes (image + alt text) to document content - **Cancel**: Discards all staged changes and closes editor - **Reset**: Clears staged changes and returns preview to original state (keeps editor open) ## 🚀 User Experience Improvements - **Professional Interface**: Clean, modern design with clear visual hierarchy - **Immediate Feedback**: Real-time preview of changes without document modification - **Non-Destructive**: No accidental overwrites - changes must be explicitly accepted - **Intuitive Controls**: Standard edit/cancel/reset pattern familiar to users ## 🔧 Technical Enhancements - **Memory Efficient**: Removed redundant replaceImage method, integrated into main editor - **Event-Driven**: Proper drag/drop event handling with prevent default - **State Management**: Comprehensive staging state tracking with change detection - **Error Prevention**: File type validation and graceful error handling Added comprehensive test suite with 7 tests covering all new functionality. All image editing workflows now provide professional, non-destructive editing experience. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
