Disservin/fastchess

AI Summary: The issue describes a problem where the `fastchess` Windows executable (v1.4.0-alpha) doesn't properly terminate engine processes when interrupted with Ctrl+C. The task is to investigate why engine processes aren't terminated and a `quit` command isn't sent to them, potentially referencing the changes made in pull request #846 which disabled last trace logs. The solution likely involves modifying the signal handling within the `fastchess` application to ensure proper cleanup of engine processes upon interruption.
