atlas 170fd817ea fix(hivectl): ask the daemon whether an agent exists
The agents root is 0700 and owned by the daemon's user, so hivectl's
client-side existence guard hit EACCES on traversal for anyone not root.
It reported that as "this command needs root; re-run with sudo", which
turned three verbs' pre-flight check into a permission error about the
wrong thing: `choom`, `subvol upgrade` and `subvol snapshot create` all
failed at the guard rather than at whatever they actually needed.

The daemon runs as the owning user and already answers this question for
its own provisioning paths, so expose it on the host socket as
`AgentExists` and have hivectl ask. Operators reach that socket through
the `hive-admin` group, so the guard now works without sudo.

`choom` still needs root for `machinectl shell` — we ship no polkit rule
granting those actions — so it now checks the effective uid and says so
directly instead of failing later inside systemd's authorisation.

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, jobs::DagView) stay in hive-sh4re — this crate is only the protocol envelope, no server or client implementation.

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.
