exact_hull_quadratic : bool
If True, quadratic constraints (polynomial degree 2) are
reformulated using the exact hull instead of the standard
perspective function. Convex quadratics are handled via a
rotated second-order cone reformulation; concave quadratics
use a linear McCormick-based relaxation; and mixed-curvature
quadratics fall back to the standard perspective function.
