Dariusz L 2778b8df9f Add ShapeTool for custom output area selection
Introduces ShapeTool to allow users to define custom polygonal output areas by holding Shift+S and clicking to add points. The selected shape is used to crop and mask images and layers, and is visualized on the canvas. Updates Canvas, CanvasIO, CanvasInteractions, CanvasLayers, CanvasRenderer, and types to support shape-based output areas, including shape-aware import, export, and rendering logic.
