Semi-implicit (symplectic) Euler — first order, energy-bounded.
a = f(x, v, t)
v += a · dt
x += v · dt (the *new* velocity)
§38's recommended default for simple real-time rigid motion, and the shape of
the MotionComponent update (which additionally applies damping and the
speed clamp between the two half-updates). Under constant acceleration it
leads the exact solution by 0.5 · a · t · dt.
