Restate the condition in every destructive write

// before: decided on an earlier read, executed unconditionally
await db.delete(items).where(eq(items.id, id));

// after: the condition travels with the write
const [gone] = await db.delete(items)
  .where(and(eq(items.id, id), eq(items.isDeleted, true)))
  .returning();
if (!gone) return; // restored meanwhile: keep it
