Removed delegating methods to CanvasState from Canvas.js and updated all references to use canvas.canvasState directly for state operations (undo, redo, saveStateToDB). Updated CanvasInteractions.js, CanvasIO.js, CanvasLayers.js, and CanvasView.js accordingly. Updated REFACTORING_GUIDE.md to reflect the completion of this refactor.
