Detailed Description

minmod limiter: TVD (Total Variation Diminishing), 2 ghosts, order 2 in smooth regions.

Returns min(|a|,|b|)*sgn(a) if a and b have the same sign, 0 otherwise. Implemented without std::min / std::abs to stay device-safe (no <cmath> required). Order 1 locally at extrema (clips smooth peaks): prefer VanLeer when smooth growth modes must survive.
