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

This PR uses the `mkCongrSimpForConst?` API in `simp` to reduce the number of times the same congruence lemma is generated. Before this PR, `grind` would spend `1.5`s creating congruence theorems during normalization in the `grind_bitvec2.lean` benchmark. It now spends `0.6`s. This PR should make an even bigger difference after we merge #9300. |
