/**
 * Ollama Provider Implementation
 *
 * Implements the Provider interface for Ollama's OpenAI-compatible API.
 * Ollama provides local LLM inference with an API that mirrors OpenAI's format.
 *
 * Key characteristics:
 * - Local server running at http://localhost:11434
 * - No authentication required (local)
 * - Uses OpenAI-compatible /v1/chat/completions endpoint
 * - May not support all features (especially function calling)
 * - Server may be slower than cloud providers

/**
 * Ollama provider adapter for local LLM inference.
 *
 * Ollama provides an OpenAI-compatible API for running local models.
 * This provider translates Foundation requests to the Ollama format
 * and handles the specific characteristics of local inference.
 *
 * Features:
 * - No authentication required (local server)
 * - Supports streaming responses
 * - Limited function calling support (depends on model)
 * - Graceful connection error handling
