 * - volcengine: Uses structured_outputs for best performance with JSON schema responses
 * - openai, azure-openai, anthropic: Use native tool calling capabilities
 * - Default fallback to native for maximum compatibility
 *
 * @param provider - The model provider name
 * @returns The recommended tool call engine type for the provider
