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

This PR prevents `exact?` and `apply?` from suggesting tactics that correspond to correct proofs but do not elaborate, and it allows these tactics to suggest `expose_names` when needed. These tactics now indicate that a non-compiling term was generated but do not suggest that that term be inserted. `exact?` also no longer suggests that the user try `apply?` if no partial suggestions were found. This addresses part of #5407 but does not achieve the exact expected behavior therein (due to #6122). |
