feat: enhance canvas functionality with new node types and improved data handling
- Added support for a new "compare" node type to facilitate side-by-side image comparisons. - Updated AI image and prompt nodes to include aspect ratio handling for better image generation. - Enhanced canvas toolbar to include export functionality for canvas data. - Improved data resolution for compare nodes by resolving incoming edges and updating node data accordingly. - Refactored frame node to support dynamic resizing and exporting capabilities. - Introduced debounced saving for prompt node to optimize performance during user input.
