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

This PR enables the elaboration of theorem bodies, i.e. proofs, to happen in parallel to each other as well as to other elaboration tasks. Specifically, to be eligible for parallel proof elaboration, * the theorem must not be in a `mutual` block * `deprecated.oldSectionVars` must not be set * `Elab.async` must be set (currently defaults to `true` in the language server, `false` on the cmdline) To be activated for downstream projects (i.e. in stage 1) pending further Mathlib validation. |
