'nonreflecting' ghost: characteristic (LODI/Thompson) non-reflecting BC.
Two variants are selected by nrbc_mode: 'pressure' (isentropic pressure-relaxation) and 'characteristic' (full LODI characteristic targeting). Each retains its exact per-side ('L'/'R') and per-Mach-regime branches. @p no_write is set .true. for the supersonic-inflow guards that must leave the halo untouched.
