- variables.nix: switch to rec {}, extract giteaDomain/giteaRepoPath,
extraAdminSshKeys, haLanNfsFqdn, tailscaleResolverIp, ports.dhcp,
ports.dns; ipaServer now derives from homeDomain ref; section headers
- modules: use new vars throughout (pxe-boot, ts-dns-forwarder,
cluster-config, configuration.nix, mount-pxe-images) — eval unchanged
- docs: delete ephemeral planning docs (AUDIT_REPORT, ha-network-audit,
network-cutover); add docs/ha.md; drop migration reference table from
ip-addressing.md; remove stale server example from beszel.md
- CLAUDE.md/README.md/AGENTS.md: fix build types (tailscale-router,
ha-server, drop server); document scripts/ha/, scripts/ipa/, and
all previously undocumented top-level and lib scripts

NixOS's dnsmasq module defaults resolveLocalQueries to true, which adds
127.0.0.1 to networking.nameservers and binds dnsmasq to listen-address=127.0.0.1.
This made the host route all its own DNS through dnsmasq, which had
no-resolv=true and no upstream for anything outside the tailnet domain —
so every non-tailscale DNS query from the host itself (including SSSD
resolving the IPA server FQDN after the IPA client module was added) failed.
Setting resolveLocalQueries=false limits dnsmasq to its intended role: a
forwarding proxy reachable on the LAN interface for IPA's conditional
forwarder. The host uses domainControllerIp directly (already set in
networking.nameservers in host.nix).

IPA refuses to create a forward zone for ts.net because it's a real
public TLD with DNSimple nameservers. The forward zone must use the
tailnet-specific subdomain (vars.tailnetDomain, e.g. tail13f623.ts.net)
instead. Update dnsmasq server selector and comments to match.

FreeIPA (the new authoritative DNS) cannot reach 100.100.100.100
(Tailscale's internal MagicDNS resolver) directly because the DC is not
a Tailscale node. The tailscale-router IS a Tailscale node and can
reach 100.100.100.100 via tailscale0, so it now runs a dnsmasq
instance on its LAN interface that forwards all ts.net queries to
Tailscale's resolver.
After deploying this host, configure FreeIPA with:
kinit admin
ipa dnsforwardzone-add ts.net \
--forwarder=192.168.2.222 \
--forward-policy=only
This replaces Pi-hole's conditional forwarder for ts.net and restores
resolution of Tailscale MagicDNS names (e.g. raspberrypi.tail13f623.ts.net)
for all LAN hosts using FreeIPA as their DNS server.
