Have Claude generate language test data for the languages currently missing from src/ts/tests/language_data/ — the README claims coverage of Italian and Punjabi but no test data exists for them. Existing files (english.json, german.json, french.json, spanish.json, hebrew.json, russian.json, ukrainian.json, belarussian.json, bengali.json, portuguese.json, emoji.json) define the expected schema.
