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. 🤖 Prepared with Claude Code Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com> (cherry picked from commit 5dd8d57)
