Delayed escalation dice bot script (Lua)

-- Delayed Escalation (low chance / high payout with pre-roll)
-- Bet the minimum for the first `preroll` losses in a row, then start multiplying.
-- At 3.35% chance the payout is ~29.5x, so one hit after a long drought clears the
-- escalation. The pre-roll keeps turnover tiny while waiting for the streak to mature.
