 * Heuristically detect the language of the given text using franc.

 * Returns 'unknown' when:
 *   - text is shorter than MIN_TEXT_LENGTH characters
 *   - franc returns 'und' (undetermined)
 *   - the detected language is not in LANGUAGE_CODE_MAP
 *   - confidence is below MIN_CONFIDENCE
 *
 * This is a helper heuristic — it does not affect the pseudonymization pipeline.
 * The --lang config flag remains the authoritative language selector.
