applyNegDifferential F G = 0 ∨ RealStable (applyNegDifferential F G)
applyNegDifferential F G denotes the operator F(-∂) {G}. The final signature should use the real-stability/multivariate API chosen in #87.

Notes
This theorem is the second main stability input for Gribinski--Marcus Theorem 2.3. It should be proved or imported in a general enough form to apply to the polarized p and q polynomials in the proof of the rectangular additive convolution theorem.
