feat: flatten ComfyUI workflow structure for web UI visibility

Update workflows/link-comfyui script to link individual JSON files directly to /workspace/ComfyUI/workflows/ instead of subdirectories. ComfyUI web UI requires workflows to be in the root workflows directory to display them.

Changes:
- Remove old directory symlinks
- Link all 20 workflow JSON files directly to workflows root
- Preserve original descriptive filenames (e.g., flux-dev-t2i-production-v1.json)
- Add workflow count display
- Keep README and WORKFLOW_STANDARDS documentation links
