/**
 * Ollama LLM Provider
 *
 * Implements LLMProvider interface for local Ollama models.
 * Extends OpenAICompatibleProvider for shared functionality.
 *
 * @example
 * ```typescript
 * const provider = createOllamaProvider({
 *   model: 'llama3.2',
 *   baseUrl: 'http://localhost:11434'
 * });
 * ```
 *
 * @remarks
 * - Requires Ollama to be running locally
 * - Default model is llama3.2 (supports tool calling)
 * - Extended thinking is not supported (Claude-specific feature)
