normalize method
Implementation
Tensor normalize({double eps = 1e-12}) {
// This calls your optimized C++ L2 Row Normalize
final h = engine.layerNorm(_handle, eps);
final out = Tensor._raw(h, shape);
// CRITICAL: If your C++ engine doesn't automatically link children
// for autograd, you must do it here:
// out._children = [this];
return out;
}
