Erich Blume 96dbbb3cbe C0: add sn2-prelaunch wrapper to clear SN2 stale lockfiles
UE5 writes Saved/running.dat as a "session in progress" marker. If
the previous session exited uncleanly (SIGKILL, crash), it lingers,
and SN2 pops up an invisible 0×0 Error dialog at next launch that
the GameThread blocks on forever — visible only as a black screen
with a spinning loader. Wrap the Steam command to clear the marker
files before each launch.

Add sn2-prelaunch Steam launch wrapper on ringtail that removes Subnautica 2's stale Saved/running.dat and Saved/beforelobby.dat lockfiles before each launch. SN2 pops up an invisible (0×0-sized) Error dialog when it detects an unclean exit, blocking GameThread forever; this is observable only as a black screen with a spinning loader. Use via Steam launch option: sn2-prelaunch %command%.
