/**
 * G6.5 — status line renderer for the peaks-code batch-sync wait period.
 *
 * Single line, 80-120 chars, status-line-friendly. The shape is
 * documented in PRD §G6.5:
 *
 *   [peaks-code] swarm 3/3 running | rd-planning 45% (12s ago) | qa-test-cases 30% (5s ago) | ui-design 20% (2s ago)
 *   [peaks-code] swarm 3/3 running | rd-planning 70% (8s ago) | qa-test-cases 50% (3s ago) | ui-design 30% (6s ago)
 *   ...
 *   [peaks-code] swarm 3/3 done in 47.3s
 *
 * Pure helper; the poller calls it once per tick. No IO.
