atlas 07852cabc1 feat(3088): move the gateway's nginx + dnsmasq onto the host
The gateway's nginx + dnsmasq no longer run in their own nspawn container.
`nix/host-modules/hive-gateway/default.nix` loses the
`containers.hive-gateway` wrapper and everything that existed only to punch
holes in it: `privateNetwork = false`, `CAP_NET_ADMIN`, five bind mounts,
its own `stateVersion`, `networking.firewall.enable = false`,
`networking.resolvconf.enable = false`, and the `hive-gateway-resolv`
path+service pair. 465 -> 303 lines.

The container never bought isolation here. It shared the host netns by
necessity — nginx binds the host's :80/:443, dnsmasq answers on the bridge —
so each of those settings was undoing a boundary the gateway could not
afford in the first place.

Four things made it more than a deletion, none of them visible in the nix
diff:

- The self-signed cert service also imports the hive CA leaf, so removing it
  with the container would have left nginx naming a missing cert file, which
  it refuses to load at all.
- The nginx reload is a hive-priv verb. It still needs root, but no longer
  for the reason its doc gave, and `--machine=` was both transport and
  scope — so the unit name is now hard-coded in the helper as the
  containment.
- The lifecycle verb named a container that stops existing.
- `journalctl -M hive-gateway` had no machine to enter.

Per the operator's ruling, the operator verb keeps working and agents lose
it. `InfraContainer` answered three questions that used to share an answer;
it now splits into `name()` (identity), `target()` (Container vs HostUnit),
`service_unit()` (the systemd unit), and `agent_restartable()`, which the
MCP restart path checks before the capability so the refusal cannot read as
"ask for infra_admin". `SIBLING_CONTAINERS` drops the gateway — it gates the
requests that name a container as a string — while `FromStr` still accepts
it, because that answers what a name is, not who may act on it. The
dashboard's gateway journal reads host journald filtered to `nginx.service`.

Prose was corrected where it only named a location, and re-argued where the
container was doing security work: a `0666` per-agent socket was safe
because only the gateway container had the directory bind-mounted. There is
no mount now, so the directory permissions are the whole of the access
control — the constraint holds, its mechanism doesn't.

Gate: nix fmt / clippy --all-targets -D warnings / cargo test all clean (710
tests); hivectl-cli.md regenerated from the clap tree. The nix eval was run
in both TLS shapes at this commit: every delta in the rendered
virtualHosts is one of the three intended path moves, dnsmasq settings are
byte-identical, and the absence probe flips true -> false with bindMounts
emptied.

hive-host-sock

Wire types for the host admin socket (/run/hyperhive/host.sock) — the host-control protocol spoken between the hivectl operator CLI and the hive-c0re daemon.

Why it's its own crate

Re-homed out of hive-sh4re so a standalone hivectl depends on just this protocol crate instead of the whole daemon-shared crate. hivectl drives the full hive (spawn / kill / destroy / rebuild / deploy) over this socket without linking hive-c0re; keeping the request/response shapes here is what makes that thin dependency possible.

Shape

Serde-derived request/response enums for the host admin protocol. The larger shared payload types some variants reference (Approval, AgentStatusRow) stay in hive-sh4re — this crate is only the protocol envelope, no server or client implementation.

Its own jobs module is the exception: the job-queue vocabulary hivectl needs (Source, State, PermPayload, NodeId) is protocol-local. The typed DagView/NodeView projection that used to live there is gone — the queue is served as a generic graph (hive-jobq-wire), not as a second hand-written view.

See docs/boundary.md (host admin socket access) for the trust model around who may connect to the socket, and hive-priv-sock for the sibling split on the privileged-helper socket.
