GET /api/agents/{name}/bash-tasks reads the agent's keys of the bash-task-status
bucket and reports each task's state, command and times, with a live task whose
daemon stopped reporting as stale. The swarm UI shows them in a background tasks
section of the agent card, running ones first. The task output stays unread.
The roster loses its second column and its table view. Selecting a card opens
its details under it as four folded sections: overview, settings, accounts and
the terminal. The status, message and wanted rows, which the card header
already shows, are gone from the details. The terminal page's details dialog
keeps the flat list.
