One shared `stableArray(prev, next)` helper replaces the duplicated element-equal/keep-prev logic in both stores, and freezes the shared ref so a future in-place mutation fails loud instead of silently corrupting the cache. Computed return type is now `readonly string[]` (it always was, immutably).
