Bug

The image tool rejects all ollama/ provider models with 'Unknown model' even after the fix in #59943 (2026.4.14).

Environment

• OpenClaw 2026.4.14 (323493f)
• macOS Darwin 25.4.0 (arm64)
• Node v25.6.1

Config

"imageModel": {
  "primary": "ollama/gemma4:e4b",
  "fallbacks": ["ollama/kimi-k2.5:cloud", "ollama/llava:13b"]
}

Models are registered and visible via openclaw models list:

ollama/gemma4:e4b          text+image 128k  yes  yes  image
ollama/kimi-k2.5:cloud     text+image 128k  yes  yes  img-fallback#1
ollama/llava:13b           text+image 4k    yes  yes  img-fallback#2

Error

All image models failed (3): 
  ollama/gemma4:e4b: Unknown model: ollama/gemma4:e4b
  ollama/kimi-k2.5:cloud: Unknown model: ollama/kimi-k2.5:cloud
  ollama/llava:13b: Unknown model: ollama/llava:13b

Verification

• Direct ollama API calls work perfectly: curl http://127.0.0.1:11434/api/generate with model gemma4:e4b and images returns correct results
• normalizeModelRef('ollama', 'gemma4:e4b') returns {provider: 'ollama', model: 'gemma4:e4b'} correctly
• The fix code IS present in dist/image-DQ3Bkt42.js line 23
• Full gateway restart does not resolve
• openclaw doctor --non-interactive shows no errors

Hypothesis

The model registry find('ollama', 'gemma4:e4b') call is not matching ollama models. The models are registered under models.providers.ollama in config but the image tool's registry instance may not be the same one populated from that config path, OR the find() method is using a different key format than what the ollama provider registration produces.
