- 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

core.nix is the new minimal layer: user, SSH, fish, nix flakes/gc,
locale, and a handful of essential packages. Suitable for any headless
host that just needs to be SSHable and manageable.
base.nix now imports core.nix and adds the day-to-day quality-of-life
layer: avahi, mosh, direnv, nix-ld, earlyoom, zramSwap, CLI tools,
and build toolchains. All existing hosts that import base.nix are
unchanged.
bootstrap is updated to import core.nix directly instead of
duplicating the config inline.

Switch NetworkManager WiFi backend to iwd to resolve repeated
wpa_supplicant disconnects caused by nl80211 send_event_marker
incompatibility with iwlwifi. Each disconnect was triggering avahi
SIGHUP reloads, causing .local name resolution to fail for several
minutes at a time.
Also disable WiFi power save in TLP and enable IPv6 mDNS resolution
via NSS (nssmdns6) for hosts that only advertise IPv6 addresses.
