Record what the wake word invents, not just what it hears (V-487) 62eef01c18

The first head woke 22 times per hour of continuous Russian speech. Two rounds
of hard negative mining over 40000 unseen Common Voice clips took that to 3.4,
and the second round recovered the recall the first had cost.

The number is crossings per hour, not accuracy per window. A 1.7% false-accept
rate on a gate that scores twelve times a second reads as small and is a wake
every few seconds.

Two things are stated rather than buried: Golos scores 2 wakes in 14 minutes at
every threshold, so a handful of real utterances sit above 0.999 and no
threshold moves them; and no negative in any table is a room recording.

Default the keyword threshold to 0.999, from the measurement (V-487) 02d96e611d

Over 65.1 minutes of held-out Common Voice the built binary woke three times
at 0.99 and once at 0.999. The recall difference was one render out of 126.
One render is worth two thirds of the false wakes.
