5.27.1
(fix): Accept a plain string for the root client’s token parameter when OAuth client credentials
are configured with a token override. The constructor overload, implementation signature, and
docstring previously typed token as typing.Callable[[], str] only, even though the client
wrapper accepts typing.Union[str, typing.Callable[[], str]] at runtime and the generated
example passes a string literal, so type checkers rejected the documented usage.
