Synchronizes Japanese and English README pairs: compares the newer edited version with the older one and updates the stale file when structure or meaning diverges. Use when maintaining README.md with README.en.md or README.ja.md, when the user asks to sync bilingual docs, catch up translations, or align JA/EN README after editing one side. Triggers: README 同期, 日英 README, bilingual README, README.en, README.ja.
