Case contract

Game status from a line score. away and home list runs per inning; home has either the same number of entries as away or one fewer (bottom half not yet played), otherwise return "invalid". When home is one short: if at least scheduled innings have started and home leads, the game is final (home wins without batting); otherwise in progress. When equal length: if at least scheduled innings are complete and the score is not tied, the game is final; ties continue into extra innings. Return ["final", "home"/"away", innings] or ["in progress", None, None].
