Z3 commit message: fix unsound grobner-quotient-pair lemma: skip lc with non-integral coefficients

pdd::reduce() can introduce non-integral coefficients via leading-term
division. The quotient lemma reasoning assumed lc_comb = lc_i - lc_j
was always integer-valued, which failed when lc had non-integral coefficients.
Filter out such entries when building var_to_facts.
