chess 960 draws are not classified

[ghost]

Chess 960 draws seem to not be classified like in standard games for some reason (i.e. threefold repetition, stalemate, etc.) On the game page, it just says “Draw”.

• https://lichess.org/T6gEs07L (threefold repetition)
• https://lichess.org/71iab27S (stalemate)

Seems like lila or scalachess doesn't categorize those two properly. It works for the other reasons which are computed based on other data but e.g. the stalemate should have game end reason "stalemate" but does have "draw". And for 3-fold, history.threefoldRepetition apparently returns false: https://github.com/lichess-org/lila/blob/master/modules/game/src/main/Game.scala/#L622 🤔

I think the example cited as stalemate (https://lichess.org/71iab27S), is actually an example of threefold repetition.

Edit: Stalemate looks to be ok unless you can find a counterexample (https://lichess.org/ruAE48lA/black#64)
