Leonardo de Moura 2d67524e42 feat: equality in grind linarith (#8697) ... This PR implements support for inequalities in the `grind` linear arithmetic procedure and simplifies its design. Some examples that can already be solved: ```lean open Lean.Grind example [IntModule α] [Preorder α] [IntModule.IsOrdered α] (a b c d : α) : a + d < c → b = a + (2:Int)*d → b - d > c → False := by grind example [CommRing α] [LinearOrder α] [Ring.IsOrdered α] (a b : α) : a = 0 → b = 1 → a + b ≤ 2 := by grind example [CommRing α] [Preorder α] [Ring.IsOrdered α] (a b c d e : α) : 2*a + b ≥ 1 → b ≥ 0 → c ≥ 0 → d ≥ 0 → e ≥ 0 → a ≥ 3*c → c ≥ 6*e → d - e*5 ≥ 0 → a + b + 3*c + d + 2*e < 0 → False := by grind ```		2025-06-09 23:39:24 +00:00
