feat: Draw by threefold repetition
A position coming up for the third time with the same side to move ends
the game as a draw, in the TUI and in training self-play. Players now get
the game's earlier boards in pick_move, and the search scores the first
repetition on its path as a draw, so a side that is ahead avoids one and
a side that is behind seeks one.
