PUNKTFUNK_VIDEO_DROP now also covers the native data plane (N% of
sealed wire packets discarded before send in paced_submit — the same
FEC-test knob the GameStream path has; no netem/root needed), and the
probe grows the real clients' recovery trigger: the data loop publishes
the session's unrecoverable-frame count and the control task sends
RequestKeyframe when it rises (100ms poll = natural coalescing).
Together these make the IDR-vs-intra-refresh recovery A/B runnable
against any host.
