signInPlace
[common]
fun signInPlace(self: Tensor): Tensor
signInPlace(self: Tensor): the sign_ operator. In-place sign: writes the result through self; same formula, arguments, and error conditions as sign(). A view input writes through its base storage. Returns self under the value surface, Result<void> under the Result surface; CLIKART_CHECK is the mode-stable spelling. Writes through self and returns it, so calls chain.
