The sync REPL proxy forwarded methods via __getattr__, so dir()/tab-completion never saw them and the sync wrapper reported (*args, **kwargs) instead of the real signature. Add __dir__ delegating to the wrapped target, and decorate the async wrapper with functools.wraps so inspect.signature()/help() report the real params + docstring.
