RegexLabels class

Every text regex_ui writes by itself: rule titles, RegexChar names, screen reader words, strength labels and field labels.

Set your language once, before the rules are built (e.g. in main). Pass only what you change; the rest stays English:

RegexLabels.current = RegexLabels(
  minLength: (n) => '$n文字以上',
  chars: {RegexChar.whitespace: 'スペース', RegexChar.digits: '数字'},
  only: (list) => '$listのみ',
  join: (words) => words.join('、'),
);

Ready languages: en, tr, de, es, fr, it, pt, ja: RegexLabels.current = RegexLabels.tr; or, from the device language, RegexLabels.forLanguage(locale.languageCode). Change a few words of a ready language with copyWith.

One rule only? Pass title: to that rule instead.
