- Remove alex from nix.settings.trusted-users in core.nix (was not in
the original base.nix and widens attack surface by allowing arbitrary
binary cache configuration without sudo)
- Restore useful comments in base.nix (zram explanation, earlyoom
purpose, avahi/systemd-resolved notes)
- Move documentation.man.man-db.enable = false into core.nix so all
hosts get it, remove redundant setting from wintermute and nightcity
