Class: Differentiation

Backend-neutral configuration for how gradients are propagated through the temporal integration. Expressed in physical/semantic terms; each backend maps it to its own mechanism (JAX solver grad_horizon / block_size, Julia adjoint sensitivity, …). Backends without autodiff (e.g. MATLAB) emit a comment noting differentiation is unsupported and proceed with the plain forward integration – they do not raise.
