terminal(background=true) spawns were only a "⚙ N" count in the status bar
while subagents got a dock, a roster, tails and controls. The classic CLI
dock now paints a Processes block under the subagent rows (command,
elapsed, latest output line; exit verdict once finished, retained 60 s),
and the Ctrl+T/F6 monitor lists processes under the agents with Enter =
log tail and x = stop that process. Processes cannot be steered.
