davideandClaude Sonnet 5 5ce49d7b88 Add round lifecycle, draw algorithm and scheduler
Periodic scheduler (configurable round duration) that closes a round
only once all broadcast bets confirm, waits for the next block after
closing, draws a winner via block-hash-seeded modulo over participants
ordered by broadcast time, triggers the 70/30 payout, and only opens the
next round once that payout confirms. Draw logic is isolated in
draw.py as a deliberately simple, replaceable component.
