# 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
