Summary:

Ulterior Motive

Unblock the tanh activation in native MaxViT execution.

Rationale

What: Dispatch aten.tanh.default through the existing unary lowering and ggml_tanh kernel.

Why: The graph builder rejects the operator even though ggml already implements it.

Details

• Reuse the existing floating-point validation and unary input handling.
• Check contiguous and transposed inputs with cached and uncached execution.
• Cover signed zero, infinities, NaN and integer-input rejection.
