ci: bump version with Build-142

The tournament stream broadcasts a gameStart per color for every pairing in
the round, without a player id. The bot latched the first color it saw and
played games it was not part of, submitting moves for the wrong color that
the server rejected. Now it fetches game detail and matches its botId against
white/black to resolve its real color, skipping games it is not in.
