orchestration: sub agents render in live panels on the multiplexer screen

Feed panes in the multiplexer (vpane_* control commands, main-vertical layout, header row),
src/orch (board, panel, formatter, transport, CAP adapter), Agent observer and cancel flag,
supervision (idle warn/cancel, user close cancels, soft then hard stop), CAP answers collected
through the spill path. Research archived under background-work-limits.
