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

This PR improves the slice API with lemmas for `drop`/`take` operations on `Subarray` and more lemmas about `Std.Slice.fold`, `Std.Slice.foldM` and `Std.Slice.forIn`. It also changes the `simp` and `grind` annotations for `Slice`-related lemmas. Lemmas converting between slices of different shapes are no longer `simp`/`grind`-annotated because they often complicated lemmas and hindered automation. |
