Change: Add ComfyUI local image engine

Why

TrueGrowth needs local image generation that can actually execute downloaded models while keeping business workflows, canvas generation, task center, and media library under TrueGrowth control.

What Changes

• Add ComfyUI as a local image engine, not as the full business workflow engine.
• Add local API endpoints for ComfyUI status, model inspection, templates, and image generation.
• Route ComfyUI generation results into the existing local task and media asset flow.
• Surface ComfyUI status and templates in Model Center so users can understand missing models or nodes.

Impact

• Affected specs: image-generation, runtime-model-discovery
• Affected code: local runtime API bridge, workbench runtime client, Model Center, image engine entry points
