Lean 4 fork for HoTT-compatible kernel extensions (Path types, transport, HITs). Maintained against upstream leanprover/lean4.

This PR implements equality propagation for `Nat` in `grind order`. `grind order` supports offset equalities for rings, but it has an adapter for `Nat`. Example: ```lean example (a b : Nat) (f : Nat → Int) : a ≤ b + 1 → b + 1 ≤ a → f (1 + a) = f (1 + b + 1) := by grind -offset -mbtc -lia -linarith (splits := 0) ``` |
