Legacy heuristic aerodynamic-jump model. NOTE: the trajectory solver uses the validated litz_crosswind_jump_moa estimator instead; this self-calibrated model (with a hand-tuned magnus_enhancement factor and a known horizontal-sign quirk) is retained only for backward compatibility with external callers.

Calculate aerodynamic jump for a spinning projectile.

Aerodynamic jump is the displacement of the projectile’s trajectory as it transitions from constrained motion in the barrel to free flight.
