Continuity counted 'host actuator raven is not attached' as a workload
death and burned all three restart attempts inside the reattach window
after an Idunn restart, demoting a healthy Muninn. The hub now returns a
typed HostUnobservable for not-attached, detached, reconnected and
unanswered, and supervision skips the tick instead of restarting.
A route-less host workload that owns fixed host resources (one desktop,
one capture, fixed advertised ports) cannot overlap two incarnations. A
binding may now declare rollout strategy stop-then-start: the admitted
incumbent is stopped at Starting, before the candidate starts, and
supervision leaves the target alone from Starting on. A systemd-transient
workload still rolls out candidate-then-promote only.
