feat: add duel countdown overlay (3-2-1-Fight!)

Browse source 
Parse SMSG_DUEL_COUNTDOWN to get the countdown duration, track the
start time, and render a large centered countdown overlay. Numbers
display in pulsing gold; transitions to pulsing red 'Fight!' for the
last 0.5 seconds. Countdown clears on SMSG_DUEL_COMPLETE.
