Error message: ScaledMatmul custom call contracting dimension index out of bounds.

The __op$block_scaled_dot custom call performs matrix multiplication on MXFP8-quantized tensors. The compiler checks the first configured contracting dimension for each operand, or the last dimension when none is configured, and raises this error when that index is negative or greater than or equal to the operand rank.

To fix this error, use dimension indices within the valid range (0 <= dim < rank).
