atlas 0e1a975f9f fix(3179): the gateway's config files get their own state dir
`agents.conf` and `gateway.htpasswd` move from /var/lib/hyperhive/gateway
to /var/lib/hive-gateway/conf, alongside the `tls/` the gateway already
kept there.

nginx reads both as an unprivileged user. Under c0re's state dir it could
only reach them by traversing a directory systemd re-declares `0750
hive-core` on every c0re start — so nginx was given `SupplementaryGroups
= [ "hive-core" ]`, which also handed it read access to everything else
group-readable in that tree. The tokens are individually 0600, but the
broker sqlite carries no explicit mode: every message between every agent
was readable by the process whose job is parsing untrusted network input.

Moving the files removes the need and the exposure together. The group is
gone, and its absence is now commented as load-bearing so it doesn't come
back as a fix for a symptom it would recreate.

Also drops this module's `/var/lib/hyperhive` tmpfiles rule. It declared
`0755 root root` and could never win against `StateDirectoryMode`, and a
losing declaration still reads as a guarantee — that is what sent the
first diagnosis of the outage looking for who had changed the mode.

Ordering is unchanged and still the thing that makes a fresh boot work:
tmpfiles runs before services and seeds both files empty-but-valid, nginx
names them (an `include` of a missing file is fatal, not empty), and
content arrives when c0re writes and reloads — which it does on every
topology change, so a boot against the empty seed resolves itself.

Folds in the mode fix: `write` now sets 0644 on the tmp file before the
rename, because a rename carries the source's mode and discards the
destination's, and the tmpfiles rule that declares 0644 is
create-if-absent so it never re-applies.

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.
