overlay: フォントキャッシュ追加と小型ログのルビ描画を改善
- フォントのメモリキャッシュ(_font_cache)と _get_font を導入し truetype 読み込みを最適化 - createTextboxSmallLog を堅牢化（None対応、幅測定の例外処理、改行判定の改善） - 単語単位ルビ描画機能を追加（renderRubyBlock / createTextboxSmallLogWithRubyTokens） - トークン毎の幅算出／センタリング、行折り返し検出時のフォールバック実装 - createOverlayImageSmallLog を拡張して、元文・翻訳それぞれにルビ適用とフォールバック合成を実行 - __main__ のテスト呼び出しを翻訳リスト形式に合わせて修正し、ルビテスト追加
