No tracking of loss of final life token

The current set-up of the `stats` log records the current number of life tokens on a given turn. This means if a move is taken that causes the loss of a life token, this loss will only be recorded as a "lost life" in the following turn. Therefore drawing the life-lost data from the `stats` logs will not include the loss any final, game-losing life token, as after the game is lost no further turns are recorded in this log. This issue can be rectified with a final "wrap-up" entry included after the last turn of a lost game.

Start by locating where the `stats` log records life tokens after each turn and where a lost game ends. Trace the final move and its logging path, then verify that a final wrap-up entry records the last lost life token without adding another turn.
