Kim Morrison 8154aaa1b3 feat: preparation for semirings and noncommutative rings in grind (#8343) ... This PR splits `Lean.Grind.CommRing` into 4 typeclasses, for semirings and noncommutative rings. This does not yet change the behaviour of `grind`, which expects to find all 4 typeclasses. Later we will make some generalizations.		2025-05-15 11:25:57 +00:00
