companion: wave goodbye on hide

SUPER+\ now plays a short goodbye instead of dropping her at once: she cycles wave-l and wave-r around the existing wave for a sway, then the normal drop. One hide in four she also says a bye line, non-forced so the usual 30 s cooldown applies; the hold matches what showed, 2 s with a line and 1 s silent.

The sway is klein edits of dress/wave rather than base, so the arm stays up and only the hand moves; the leotard twins come from their dress frames. The leotard rerolled to seed 7 because the first seed left a faint alpha fringe that widened the canvas and made the flip jitter.

Fullscreen, the lock screen and the monitor hop keep their own exits and do not wave.

Also carries the pending onFocusedChanged guard: with no focused monitor, or already away, she moves at once rather than waiting for an exit that will never settle.
