cream

cream のリリースノート・リリース準備資料を作成する。前バージョンからの変更を git log / merged PR から収集し、.local/v<version>-release-note/ に 3 ファイル構成（all.md=全変更リスト / highlight.md=ヘッドライン級のみ / release-note.md=GitHub Release に貼る英日併記本文）でまとめ、バージョン bump〜publish 確認までのリリース手順を案内する。Use when: "release note を書きたい", "リリースノート", "リリース準備", "次バージョンの変更をまとめて", "release notes for the next version".

Build a golden snapshot test for a cream.kt KSP feature/annotation by horizontally extending the established @CopyTo / @CopyFrom pattern. Use whenever the user wants to add, build, or "横展開" (roll out) a `<Feat>SnapshotTest` for a cream annotation — @CopyToChildren, @SealedCopy, @CombineTo, @CombineFrom, @CopyMapping, @CombineMapping (or any cream annotation) — including replacing a `<Feat>SnapshotTest` xtest stub, building scenario families, or getting golden coverage for cream's generated copy/combine functions. Trigger even if the user just names a feature and says "add the snapshot test" without mentioning copyTo or copyFrom. This is for the cream.kt repo (me.tbsten.cream KSP plugin) specifically.
