chore: drop omarchy pkg-* compatibility shims

These existed only to ease muscle-memory from Arch-based distros and add
no behavior on a Nix-native system:

- nomarchy-pkg-install — alias for nomarchy-pkg-add
- nomarchy-pkg-drop    — alias for nomarchy-pkg-remove
- nomarchy-pkg-aur-add — stub that only printed "AUR doesn't exist on NixOS"

The single code caller (nomarchy-voxtype-remove) was removed in the prior
commit, so the shims have no remaining references. SKILL.md updated to use
nomarchy-pkg-add and to point at `nix search nixpkgs` instead of the AUR.
