The disk sampler ran `du -sxb` as the unprivileged hive-core user over
each agent's state/, work/ and container rootfs. hive-core cannot read
the rootfs or all of the agent-owned files, so `du` failed and each
failed path silently counted as 0: the dashboard showed a few MB for
agents using over 13 GB.
Add a hive-priv `MeasureAgentDisk { agent_name }` op. hive-priv
validates the name, derives the three paths itself (the request carries
no path), skips the ones that don't exist, and runs one
`du -s -x -b -c -P` as root with a 10 min timeout. A timeout, a non-zero
exit or output without a `total` line is an error.
hive-c0re calls it every 30 min instead of running `du` every 5 min:
each pass walks every agent's full tree as root on the disk the agents
work on, and the sizes move slowly. A failed measurement is cached as
None, so `disk_bytes` is null, the OTel storage.usage sample is omitted
and the dashboard shows "unknown", never 0.
`Coordinator::agent_work_dir` had no other caller and is removed.
Closes #4956

hive-priv-sock
Wire types for the hive-priv privileged-helper socket
(/run/hive/priv.sock) — the contract between hive-priv (the root helper,
server) and hive-c0re (client, via its priv_client).
Why it's its own crate
Split out of hive-sh4re so hive-priv — a root-privileged binary —
depends on just this narrow protocol crate instead of the much larger
daemon-shared crate. Two wins: fewer dependencies in a root process's supply
chain, and a small, self-contained interface makes the privilege boundary this
crate encodes easier to audit. Mirrors hive-host-sock's split for the host
admin socket.
Shape
Serde-derived request/response types only — no server or client logic. Both
sides import them so the shapes stay in sync. See docs/trust-boundary/boundary.md +
docs/trust-boundary/security.md for the privilege boundary these types sit on, and
hive-priv/README for the helper itself.
