Detailed Description

Implicit time integration via a user-supplied LinearSolver.

advance(u, solver, params) – fixed-step backward Euler, no observer advance(u, solver, params, obs) – same, with step callback

The field type is constrained by the VecField concept: any object exposing .vec() -> Vector& works (Vector itself, ScalarField2D, ScalarField3D, ...). This keeps ode/ independent of the fields/ module while supporting all types.
