Description
Currently only the float3 function is implemented.
It would be great to have something like this please:
public static double3 mul(quaternion q, double3 v)
{
double3 t = 2 * cross(q.value.xyz, v);
return v + q.value.w * t + cross(q.value.xyz, t);
}

Locate the existing quaternion multiplication function for float3 and inspect the surrounding double3 and quaternion APIs. Add the corresponding double3 overload using the behavior shown in the issue, then run the repository's existing build and tests to verify the new function matches the float3 version.
