mattn/go-sqlite3 は CGO 必須だが、Apple Silicon マシン上で
GOOS=darwin GOARCH=amd64 go build するとクロスコンパイル扱いとなり
Go が CGO_ENABLED=0 をデフォルトにしてしまっていた。結果 Intel Mac 向け
バイナリは stub 状態で配布され、起動直後に
"go-sqlite3 requires cgo to work" で死亡 → 「処理が予期せず終了しました」
「起動に失敗しました」が連続表示されていた。

scripts/build-backend.sh と .github/workflows/release.yml の macOS 向け
ビルドで CGO_ENABLED=1 と CC/CXX のアーキ指定を明示し、クロス CGO
ビルドが再現性高く成立するようにした。Windows/Linux の同様の明示は
スコープを切り分けるため #47 に分離。
