 * Create the built-in readability analyzer using language-specific algorithms:
 * Flesch Reading Ease → CEFR (en), Wiener Sachtextformel (de), LIX (fr),
 * Gulpease (it). English syllable counting uses the `syllable` npm package,
 * loaded lazily on the first `analyze()` call. German syllable counting uses
 * a local vowel-group heuristic. French and Italian formulas don't need
 * syllables at all.
