clamp non-finite crossover results to bounds. When parent genes violate problem bounds, sbx_betaq can produce NaN via std::pow with a negative base, which then propagates into children. Use std::clamp guarded by std::isfinite to ensure c1/c2 are always valid.
in evolve reject initial population with out-of-bounds individuals. Previously NSGA-II would proceed with invalid genes, allowing NaN to be generated during crossover. Now it throws std::invalid_argument.
