/**
 * Factory function to create a translator instance
 *
 * Supports environment variable configuration using HAVE_TRANSLATOR_* pattern:
 * - HAVE_TRANSLATOR_PROVIDER: Translation provider ('google'|'deepl'|'libretranslate')
 *
 * Provider-specific API keys are loaded from their respective environment variables:
 * - GOOGLE_TRANSLATE_API_KEY: Google Translate API key
 * - DEEPL_API_KEY: DeepL API key
 *
 * @param options - Configuration options for the translation provider (optional if using env vars)
 * @returns Promise resolving to a translator that implements Translator
 *
 * @example
 * ```typescript
 * // Using explicit options
 * const translator = await getTranslator({
 *   provider: 'google',
 *   apiKey: process.env.GOOGLE_TRANSLATE_API_KEY!
 * });
 *
 * // Using environment variables
 * // Set: HAVE_TRANSLATOR_PROVIDER=deepl
 * //      DEEPL_API_KEY=your_key_here
 * const translator = await getTranslator();
 *
 * // Mix of env vars and explicit options (explicit takes precedence)
 * // Set: HAVE_TRANSLATOR_PROVIDER=google
 * const translator = await getTranslator({
 *   apiKey: 'explicit_key' // Overrides env var
 * });
 *
 * // Use the translator
 * const result = await translator.translate('Hello, world!', 'es');
 *
 * // Use template function for repeated translations
 * const t = translator.templateFunction('en', 'es');
 * const greeting = await t('Hello');
 * const farewell = await t('Goodbye');
 * ```
