Replaces hand-rolled fetch to /api/chat with the ollama@0.6.3 package.
The package supplies proper Accept/Content-Type/User-Agent headers and
auto-handles the Ollama protocol, fixing the CDN 403s Node's bare fetch
gets against ollama.com during filing.
Both organize and search LLM ranking now route through controller/ollama.js.
