Title: nix profile wipe-history Command
Summary
The `nix profile wipe-history` command is used to delete non-current versions of a Nix profile, making it impossible to roll back to those specific versions. By default, it removes all non-current versions. An optional argument, `--older-than N`d, allows users to specify that only non-current versions older than N days should be deleted, as demonstrated by an example removing versions older than 100 days.
