Leonardo de Moura 2946ba04d5 fix: assert that nonlinear Nat terms are nonneg in cutsat (#7561) ... This PR fixes the support for nonlinear `Nat` terms in cutsat. For example, cutsat was failing in the following example ```lean example (i j k l : Nat) : i / j + k + l - k = i / j + l := by grind ``` because we were not adding the fact that `i / j` is non negative when we inject the `Nat` expression into `Int`.		2025-03-19 00:52:04 +00:00
