Refactor mask editor cropping and formatting in Canvas.js

Updated the mask processing logic to crop the mask based on the viewport pan position instead of scaling, ensuring accurate mask editing. Also standardized object formatting in logging and context creation for consistency.

 ## ✨ Key Features
 
-- **Freeform Inpainting Area:** Draw any custom (like a polygonal lasso tool) area directly inside the image for inpainting. The tool generates content that is coherent with the rest of the image, without requiring a brush.
 - **Persistent & Stateful:** Your work is automatically saved to the browser's IndexedDB, preserving your full canvas
   state (layers, positions, etc.) even after a page reload.
 - **Multi-Layer Editing:** Add, arrange, and manage multiple image layers with z-ordering.

 - **AI-Powered Matting:** Optional background removal for any layer using the `BiRefNet` model.
 - **Efficient Memory Management:** An automatic garbage collection system cleans up unused image data to keep the
   browser's storage footprint low.
-- **Inputs**
-    - **Image Input (optional):** Accepts a single image.  
-    - **Multiple Images:** If you need to feed in more than one image, use the **core ComfyUI Batch Image node**.  
-        - This lets you route multiple images into LayerForge.  
-        - You can then stack, arrange, and edit them as separate layers inside the canvas.
-  - **Mask Input (optional):** Accepts a single external mask.  
-    - When provided, the mask is applied directly to the **output area** of the LayerForge canvas when `Run` is triggered in ComfyUI.  
-- **Outputs**
-    - **Composite Image:** The final flattened result of your layer stack.  
-    - **Combined Alpha Mask:** A merged mask representing all visible layers, ready for downstream nodes.  
+- **Workflow Integration:** Outputs a final composite **image** and a combined alpha **mask**, ready for any other
+  ComfyUI node.

-## 🎯 Polygonal Lasso Inpainting Workflow
-
-LayerForge's newest feature allows you to draw custom polygonal selection areas and run inpainting directly within ComfyUI. This brings Photoshop-like lasso tool functionality to your AI workflows.
-
-### Setup Requirements
-
-1. **Enable Auto-Refresh:** In LayerForge's settings, enable `auto_refresh_after_generation`. Without this setting, the new generation output won't update automatically in the canvas.
-
-2. **Configure Auto-Apply (Optional):** If you want the mask to be automatically applied after drawing the shape, enable the `auto-apply shape mask` option in the Custom Output Area menu (appears on the left when a custom shape is active).
-
-### How to Use Polygonal Selection
-
-1. **Start Drawing:** Hold `Shift + S` and left-click to place the first point of your polygonal selection.
-
-2. **Add Points:** Continue left-clicking to place additional points. Each click adds a new vertex to your polygon.
-
-3. **Close Selection:** Click back on the first point (or close to it) to complete and close the polygonal selection.
-
-4. **Run Inpainting:** Once your selection is complete, run your inpainting workflow as usual. The generated content will seamlessly integrate with the existing image.
-
-### Advanced Shape Mask Options
-
-When using custom shapes, LayerForge provides several options to fine-tune the mask quality:
-
-- **Mask Expansion/Contraction:** Adjust the mask boundary by -300 to +300 pixels to ensure better blending
-- **Edge Feathering:** Apply 0-300px feathering to create smooth transitions and reduce visible seams
-- **Output Area Extension:** Extend the output area in all directions for more context during generation
-- **Manual Blend Menu:** Right-click to access manual color adjustment tools for perfect edge blending
-
-### Tips for Best Results
-
-* Use **feathering (10–50px)** depending on the **size of the image** to create smooth transitions between the inpainted area and existing content. Larger images generally benefit from more feathering.
-* Experiment with **mask expansion** (e.g., 10–20px) if you notice hard edges or visible seams.
-* Use **Output Area Extension** based on image size:
-
-  * **Extend the output area in all directions** to give the model more **context during generation**, especially for larger or more complex images.
-* If **visible seams** still appear in the inpainting results:
-
-  * Use the **Manual Blend Menu** (right-click on the mask area) to access **color and edge adjustment tools** for precise fine-tuning and seamless integration.
-* **Image placement behavior:**
-
-  * The generated or pasted image is automatically inserted into the area defined by the **blue shape** you draw.
-  * The model uses the area within the **dashed white preview outline** as the **full context** during generation.
-  * Make sure the dashed region covers enough surrounding content to preserve lighting, texture, and scene coherence.

-## 🤖 Model Compatibility
-
-LayerForge is designed to work with **any ComfyUI-compatible model**. The node outputs standard image and mask data that can be used with any model or workflow. LayerForge automatically inserts the generated image into the exact shape and position you draw with the blue polygon tool — but only if the generated image is saved properly, for example via a Save Image node.
