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

This PR adds `num?` parameter to `mkPatternFromTheorem` to control how many leading quantifiers are stripped when creating a pattern. This enables matching theorems where only some quantifiers should be converted to pattern variables. For example, to match `mk_forall_and : (∀ x, P x) → (∀ x, Q x) → (∀ x, P x ∧ Q x)` against a goal `∀ x, q x 0 ∧ q (f (f x)) y`, we use `mkPatternFromTheorem ``mk_forall_and (some 5)` to create the pattern `∀ x, ?P x ∧ ?Q x`, keeping the outermost `∀` in the pattern rather than converting it to a pattern variable. |
