Split the Agent network card into graph + cursor-following inspector
(delegation prompt, latest reply, descriptor, owned tasks, comms), add
the members board and the status-grouped task board off the agentTeam
projection with inline dependency chains, a filterable/sortable roster,
and an on-demand comms timeline over relay/mailbox/settled records.
Data rides a new /api/dsh-context/fleet route (one observeSession read
per session through the shared cold-read gate); hover, pin, owner
filter, and task focus are lifted to the view so every panel steers the
same inspector.
