feat(ollama): add cloud support with api key and model suffix detection

Add support for Ollama Cloud by detecting model names with "-cloud" suffix
and checking for API key presence. Update config to read OLLAMA_API_KEY
environment variable. When both conditions are met, automatically use
https://ollama.com endpoint; otherwise use local/configured URL.
