설명
Narrows a ShaderType to the native { kind: 'scalar' } arm (f32, i32, u32, bool).
It is false for f64T, which is its own kind so that this predicate does not treat
it as a scalar. Arithmetic type resolution uses it to detect the vector-scalar broadcast
case (isVec(a) && isScalar(b) and its mirror), where the vector operand’s type is the
result.
