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

PR #5883 added a new syntax for tactic configuration, and this PR enables it in most tactics. Example: `simp +contextual`. There will be followup PRs to modify the remaining ones. Breaking change: Tactics that are macros for `simp` or other core tactics need to adapt. The easiest way is to replace `(config)?` with `optConfig` and then in the syntax quotations replace `$[$cfg]?` by `$cfg:optConfig`. For tactics that manipulate the configuration, see `erw` for an example: ```lean macro "erw" c:optConfig s:rwRuleSeq loc:(location)? : tactic => do `(tactic| rw $[$(getConfigItems c)]* (transparency := .default) $s:rwRuleSeq $(loc)?) ``` Configuration options are processed left-to-right, so this forces the `transparency` to always be `.default`. |
