This declaration doesn't match the rest of the file - can we just do:

export type A2uiClientMessageList =  z.infer<typeof A2uiClientMessageListSchema>;

?

I think may be we don't need the declaration for client-to-server because we don't validate?

version: 'v0.9';
messages: A2uiClientMessage[];
}
