Add llava vision: use Ollama llava:7b for all image analysis, Claude as fallback

- Add _ollama_vision_call() using Ollama /api/generate with images array
- handle_screenshot: try llava first (free, on-LAN), fall back to Claude on error;
  text-only snapshots now use ollama instead of groq
- handle_vision: same llava-first/Claude-fallback pattern; caller can force
  provider='ollama' or 'claude' explicitly; stored provider_used reflects actual
  provider that ran
