Add to the middleware example to show how to wrap a ToolHandler. This middleware is very close to, but not the same as, wrapping a ToolHandler directly. The only difference is that the middleware wraps Server.callTool, which looks up the tool by name in the server's list and then calls the handler. That lookup (plus other intervening middleware, of course) is all that distinguishes this way of wrapping from a more direct wrapping.
