fix(cloud): PC-3b Start Claude on the held strip brings the agent's tab forward

composer-redo (pc3b-390-394/4-started.png): Start opened the Claude tab in the background (a create's
first agent asks for activate:false), so the person stayed on the plain Terminal and never saw the
queued prompt run. A hold released by the person's Start now creates the agent with activate:true;
a Renew-driven auto-start (possibly on a background tab) keeps the original args and never steals
focus.
