Major UI improvements across the application: MainWindow: - Integrate undo stack for field editing - Dirty state tracking with tab title indicators (*) - Save/SaveAs prompts on tab close with unsaved changes - Export menu integration in tab context menu - Tab management: close all, close left/right of current tab - Connect export system to tree widget signals XTreeWidget: - Add context menus for tree items - Quick export action for immediate saves - Export dialog action for format options - Raw data export for any item - Batch export for containers XTreeWidgetItem: - Add modified state tracking with visual indicator - Support for marking items as dirty ImagePreviewWidget: - Enhanced image display and navigation - Improved zoom and pan controls TreeBuilder: - Better handling of nested data structures - Improved child node generation Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
