feat: add comfyui-workspace-manager custom node

Added comfyui-workspace-manager plugin to arty.yml for ComfyUI workflow and model management.

Repository: https://github.com/11cafe/comfyui-workspace-manager

Features:
- Workflow management with version history
- Model browser with one-click CivitAI downloads
- Image gallery per workflow
- Auto-save and keyboard shortcuts

Note: Plugin is marked as obsolete (April 2025) as ComfyUI now has built-in workspace features, but added per user request.
