companion: sing when the Sony headphones connect

She now reacts to the headphones connecting with a short singing pose:
eyes shut, blindfold gone, mouth wide open, headphones on, a few musical
notes. The frames are new klein edits in frames.txt (dress/sing from
dress/base, leotard/sing from dress/sing), so a post-self-destruct sing
has its own art.

Detection is the island's rule (StatusPill.qml): by model prefix, since
BlueZ gives no class that says "headphones". The device's BlueZ Name is
WH-CH720N, which the alias does not affect. The reaction is a one-shot
hold in Mood.js (singHold, 4 s), placed after wave like the other event
reactions. A 4 s startup grace keeps a shell start with the headphones
already on from counting as a connection, since Bluetooth reads empty
for about 2 s.
