Updated all CanvasView.js method calls to use the new modular structure (canvasIO, canvasLayers, imageReferenceManager) as part of the Canvas facade refactor. Updated REFACTORING_GUIDE.md to reflect completed migration, document new usage patterns, and outline next steps. This improves code clarity and modularity while maintaining backward compatibility.
Changed the default log level from NONE to DEBUG in both canvas_node.py and LoggerUtils.js to improve logging visibility during development. Added js/REFACTORING_GUIDE.md with detailed documentation on the recent Canvas module refactor, outlining architectural changes, migration instructions, and developer notes.
