// Package ollama implements the go-llm v2 provider interface for Ollama
// (https://ollama.com), a local model runner that exposes an OpenAI Chat
// Completions-compatible endpoint. No API key is required; capability depends
// on whichever model the user has pulled locally, so Rules are intentionally
// empty — we trust the local user.
