@learnwy/english-learner

Auto-intercepts English messages for grammar / word-choice / expression issues (max 3 per message); auto-translates Chinese / Japanese / Korean / Spanish / other-language messages with vocabulary extraction. Also handles word lookups, phrase lookups (e.g. 'break the ice'), translation requests, and quiz/review. Logs every prose input (clean OR with issues) to `prose_log` so fluency rate is tracked over time. Pushes 3 due-for-review words at the first session of each day (spaced repetition: 1/3/7/14/30/90 days). Triggers: any English message, any Chinese message, any non-English-non-Chinese prose, single English word, idiom, '查单词', '学英语', 'what does X mean', vocabulary review. Data stored at ~/.learnwy/english-learner/ with mastery + fluency tracking.
