A class of its own so that the Streamable HTTP backward-compatibility rule ("HTTP 404 with a JSON-RPC -32601 body is a modern server") can require a well-formed JSON-RPC error object the same way the reserved -3202x codes do: from_jsonrpc assigns this class only when the error carries a string message.
