The Android uplink kept advancing `seq` while muted, so the first frame
after an unmute looked to the host like loss the width of the mute. The
de-jitter reads that as a gap: up to five concealment frames of stale
voice, and a seq gap counted in the uplink-health line. Past 600 ms the
pump's stale flush resets the chain first and hides it, which is why the
usual long mute looks fine — a quick toggle does not.
Freeze `seq` while muted, as the desktop uplink already does, so the
frame after an unmute continues the chain. `reset_stream` says it
plainly: a pause is not loss, and must not conceal or count a gap.
