review-changelog

檢查 changelog 是否需要根據最近的 commits 更新，並準備版本發佈。Use when the user wants to review or update changelogs before a version bump. Triggers on requests like "review changelog", "update changelog", "檢查更新日誌", "準備發版", or when the user invokes /review-changelog. Analyzes commits since the last git tag, drafts bilingual changelog entries, and guides through the commit-then-version-bump sequence.
