На этот раз это должно решить проблему раз и навсегда. У нас была некоторая несогласованность между версиями регулярных выражений на Ruby и JS, но теперь это больше не требуется.

> The CJK fix (d7a53ada16) introduced separate boundary patterns for Ruby and JS e…ngines in \`match\_word\_regexp\`. The Ruby engine used \`\[:word:\]\` (which includes digits), while the JS engine used \`\\P{L}\` (non-Letter). Since digits are not letters, the JS pattern treated them as valid word boundaries — causing "123Test" to match as "3Test" and standalone number watched words like "123" to match inside "abc123".
> 
> Replace both engine-specific patterns with a single unified pattern using Unicode property classes (\`\\p{L}\`, \`\\p{M}\`, \`\\p{N}\`, \`\\p{Pc}\`) that work identically in Ruby and JavaScript. This treats letters, marks, numbers, and connector punctuation as word characters in boundary checks, which fixes the number-matching bug for JS consumers while preserving the existing correct behavior on the Ruby side.
> 
> Since \`match\_word\_regexp\` no longer branches on engine, remove the now-dead \`engine:\` parameter from all 5 method signatures that threaded it through (\`match\_word\_regexp\`, \`word\_to\_regexp\`, \`regexps\_for\_action\`, \`compiled\_regexps\_for\_action\`, \`serialized\_regexps\_for\_action\`) and all call sites passing \`engine: :js\` (serializers, pretty\_text).
