The Settings agent card's render() set window.__t3mpLiveAgents from CLIENT-side
pings only (Object.keys(pingStatus).filter(ok)). Agents connected server-side —
via autoReconnect (ping:false) or a status?check=1 re-ping — are live on the
server even though this client never pinged them, so every re-render reset the
count to 0. Since upstream's t3mpHasBackend() is now `llmAvailable || live > 0`,
that clobber made the War Room show "No LLM backbone — connect an agent before
hunting" on localhost even with a genuinely-live local agent (repro: 3 agents
connected, hermes lastPing.ok on the server, yet hasBackend=false after any
detect/render).
Fix: live = max(client-pinged-ok, server-reported-live), reading the server's
own agent state (window.__t3mpServerAgents, refreshed via status?check=1). The
summary and the global now both reflect reality and re-renders no longer break
the gate. Verified: hasBackend stays true across detect/connect re-renders.
