When no agent is active, '/queue <prompt>' previously fell through dispatch with its raw text intact instead of being treated as a normal prompt. Rewrite event.text to the bare payload (mirroring the /steer no-active-agent path just below) and return a usage hint when the payload is empty. Salvaged from PR #29290 (queue half only — the /footer mid-run dispatch half already landed on main via #65521).
