feat: add logo overlay support for template thumbnails

[christian-byrne]

Summary

Adds support for provider logo overlays on workflow template thumbnails.

Changes

• index.schema.json: Added logos field to templateInfo and new logoInfo definition supporting:
  • Single provider string or array for stacked logos
  • Optional custom label, position, opacity, and gap settings
• index_logo.json: Converted from array to key-value format for frontend compatibility
• index.json: Added example logos to 4 templates (OpenAI DALL-E 3, Stability SD3.5, Google Gemini, WaveSpeed FlashVSR)

Dependencies

Requires frontend PR: Comfy-Org/ComfyUI_frontend#8365

Logo Info Schema

{
  "provider": "OpenAI" | ["WaveSpeed", "Hunyuan"],
  "label": "Custom Label",
  "gap": -6,
  "position": "top-2 left-2",
  "opacity": 0.85
}

Testing

• Schema validation passes for index.json
• Example logos added to demonstrate single and stacked usage

❌ Model Analysis Check Failed

Model configuration issues were found in your template files that need to be fixed.

Why this matters: Model configurations in templates must be correct to ensure users can download and use the right model files. Incorrect configurations will cause templates to fail.

[FAIL] Some checks failed. See report above.

Common Issues and How to Fix:

1. Missing properties.models configuration:

   • Add properties.models array to nodes that use .safetensors files
   • Ensure the array contains model name, download URL, and directory information

2. widgets_values and properties.models mismatch:

   • Ensure model filenames in widgets_values match the name field in properties.models
   • Check for exact spelling and case sensitivity

3. Markdown link errors:

   • Ensure [filename.safetensors](url) links have consistent filenames between text and URL
   • Note: Civitai links are automatically whitelisted as they use model IDs instead of filenames

4. Subgraph nodes:

   • Note: Subgraph nodes (UUID-type) are automatically skipped from model validation
   • Their model configurations are handled within the subgraph definition

Please fix these issues and resubmit.
