feat(accent): send the accent to the TV launcher

udt-tv sends the window border's three hues to the tv-debloat launcher
on the TV, which draws its focus highlight's edge as their gradient and
uses the accent for its pill edges and title glow. One HMAC-SHA256-signed
UDP datagram to port 47800; the address comes from ~/.config/udt/tv.json
and the secret is the one tv-debloat deploys. Without either it does
nothing. udt-accent starts it with the other helpers, install.sh links it.
