Detailed Description

Assembled momentum operator on the device: (A u)_i = diag_i u_i + Σ coef·u[nbr], with an optional implicit-FOU advection part (rebuilt each step from the lagged velocity): a per-cell outflow diagonal advDiag + per-face inflow coefficients over a second (face-geometry) CSR.

hasAdv=false ⇒ the pure cut-cell operator, bit-exact unchanged.
