/**
 * Translates text from one language to another using a specified translation model.
 * Supports both NMT (Neural Machine Translation) and LLM models.
 *
 * @param params - Translation configuration object
 * @param params.modelId - The identifier of the translation model to use
 * @param params.text - The input text to translate
 * @param params.from - Source language code (optional)
 * @param params.to - Target language code
 * @param params.stream - Whether to stream tokens (true) or return complete response (false). Defaults to true.
 * @param options - Optional RPC options (timeout, profiling, force new connection, etc.).
 * @returns Object with tokenStream generator and text/stats properties
 * @throws {QvacErrorBase} When translation fails with an error message or when language detection fails
 * @example
 * ```typescript
 * // Streaming mode (default)
 * const result = translate({
 *   modelId: "modelId",
 *   text: "Hello world",
 *   from: "en",
 *   to: "es"
 *   modelType: "llm",
 * });
 *
 * for await (const token of result.tokenStream) {
 *   console.log(token);
 * }
 *
 * // Non-streaming mode
 * const response = translate({
 *   modelId: "modelId",
 *   text: "Hello world",
 *   from: "en",
 *   to: "es"
 *   modelType: "llm",
 *   stream: false,
 * });
 *
 * console.log(await response.text);
 * ```
