hive-c0re publishes this hive's status to the swarm queue as the OIDC
client `hive-<name>`. Its secret came from
`deploy.hive-controller.statusPublish.clientSecretFile`, which defaulted
to authelia's minted file only on a host running both authelia and the
queue. Every other hive had no secret and never published, so the
controller showed it `never_reported`.
Now `swarm-secret-publish`, beside authelia, also copies each hive's
`hive-<name>` secret to `swarm/hives/<hive>/oidc/client`. Its policy
already allows `swarm/hives/*`. hive-c0re reads that path under the
hive's own store leaf, which the existing `swarm/hives/<hive>/*` grant
covers, and holds the value in memory.
The shared queue client no longer remembers a failed first connect for
the life of the process. A failed attempt is retried with a backoff
from 5s, doubling to a cap of 5 minutes; the dashboard banner stays up
until an attempt succeeds. The two status publishers wait for the
client instead of giving up on the first `None`, so a secret published
after boot is picked up without a restart.
Removed: the `statusPublish.clientSecretFile` option (both spellings,
now removed options with a message), its same-host default, its
LoadCredential, the assertion tying it to the other two coordinates,
and `swarm_queue_client::QueueConfig::from_env`, whose only caller was
this read. Publishing is now on wherever the queue URL and token
endpoint are set and the hive holds a store leaf.

Bounding is_running turned a hung systemctl into "not running" for
callers that record or act on the answer: the broad-stop restore set
dropped the agent, start_many could rebuild-and-restart a running
agent, reconcile could seed Offline. is_running is back to the
unbounded call it was.
The periodic workers read through the bounded running_state instead:
crash_watch (unchanged), and the swarm_agent_status publisher via the
new container_view::read_agent_status_bounded, which skips the agent
for that sweep when the unit state is unreadable. The GetAgentMeta
socket handler keeps the unbounded read_agent_status_live.
The queue's payload ceiling was justified by what the queue was about to
carry; it carries it now, so the comment says so.
The other two sites say "a hive with no queue configured". The swarm has
exactly one queue and a hive cannot lack it — only its coordinates, its
credential, or its ability to reach it. That wording is already used
everywhere else the absence is named; these two predate it.
The docs section on the agents' queue coordinates stopped at delivering
them and never said what the connection is for. It now names the subject
and the degrade rule, which is the part an operator reading an agent's
terminal at the swarm needs.
