A job that writes into the game folder leaves data/job-running.json while it runs and removes it when it ends. A
launcher closed or killed in the middle leaves it, and the next start logs it and tells the player which job did not
finish and that Rebuild the Game or Begin Installation goes on from the steps that were done.
