darken d9c8902d34 fix(reaction): Restore volume when conversation end frame never arrives
With one AirPod in the case the pod deterministically drops the
terminal 0x4B frame: the wind-down flurry ends on a transitional
status (1,2,3,0xB,4 then nothing), so the reaction never disengaged
and the volume stayed low until the 5-minute backstop (#608).
Reproduced on Pro 3 (fw 6589, 6503) and Pro 2 USB-C (fw 6814) —
all three share one firmware train; with both pods worn the terminal
always arrives.

The pod sends no frames during active speech, so any non-START frame
means the wind-down has begun and a terminal is imminent. A HOLD now
arms a short 6s fuse instead of the 5-minute backstop: if no terminal
(or fresh START) follows, the reaction disengages anyway. The fuse
must stay above ~5s — gaps up to 2.8s were observed between
consecutive wind-down frames. STARTs still arm the long backstop,
since the pod stays engaged and silent against ambient noise for
20-30s+ and a short timeout there resumes media mid-conversation.

Validated on hardware on both models: 7/7 single-pod conversations
restored exactly 6s after the last wind-down frame.
