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.
