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

This PR adds a `pp.fvars.anonymous` option (default `true`) that
controls the display of loose free variables (fvars not in the local
context).
- When `true` (default), loose fvars display their internal name like
`_fvar.42`
- When `false`, they display as `_fvar._`
This is analogous to `pp.mvars.anonymous` for metavariables. It's useful
for stabilizing output in `#guard_msgs` when messages contain fvar IDs
that vary between runs — for example, in diagnostic tools that report
`isDefEq` failures from trace output where the local context is not
available.
