Describe the bug

launching the debugger adds all visible variables to the debug env. if a large set is in scope that'll be quite obtrusive, and not exactly useful.

Steps To Reproduce

  1. nix repl -f '<nixpkgs>' --debugger
[...]
nix-repl> (x: throw "a") pkgs
  2. get spammed

Expected behavior

maybe something like added 27419 bindings instead, idk

nix --version output

nix (Lix, like Nix) 2.93.0-dev-pre20250318-3fcf823
