test(track): freshen rotation passes before the arrival probe and retry an inconclusive timeout

Browse Source 
A headless SwiftShader run showed a 926 ms first frame on the military probe,
which no wall-clock budget can accept: the 1 s idle refresh may already have
run inside it. Raise moveEnd and wait one frame before each attempt so the
settle frame is measured against a pass that just ran, and treat a timeout
(never a wrong angle) as inconclusive with one more attempt. Document why the
per-phase budget stays at half the refresh interval.
