- Use nixpkgs.hostPlatform module instead of deprecated system arg to lib.nixosSystem
- Rename services.logind.powerKey to services.logind.settings.Login.HandlePowerKey

All nodes now list 1.1.1.1 and 8.8.8.8 as fallback nameservers after
MCNS. When MCNS is down, internal names (.svc.mcp.metacircular.net)
fail but external DNS (google.com, github.com, etc.) keeps working.
Lesson from 2026-04-03 incident: without fallbacks, MCNS failure
caused total DNS blackout including external services, forcing
Tailscale to be disabled to restore any DNS resolution.

The previous commit removed the systemd service that stripped Tailscale's
~. DNS catch-all, breaking all DNS resolution — even when Tailscale is
disconnected. Restore it as fix-tailscale-dns, which restricts tailscale0
to only route ~scylla-hammerhead.ts.net queries.

Install mciasctl, mciasgrpcctl, mcrctl, and mcproxyctl via new
configs/mcpkg.nix module. Adds flake inputs for mcias, mcr, and
mc-proxy from git.wntrmute.dev.

Link-level DNS from DHCP and Tailscale takes priority over global
nameservers in systemd-resolved. Use domain routing (~mcp.metacircular.net)
so resolved sends only internal zone queries to rift's CoreDNS.

rift: sysctl to allow rootless containers to bind port 53, open
firewall for DNS queries from LAN clients.
vade: point nameservers at rift (LAN + Tailscale) for internal
service resolution via CoreDNS (MCNS precursor). Falls back to
1.1.1.1/8.8.8.8 via systemd-resolved.
