SV_SpawnServer reinitializes the game module, invalidating all
entity and configstring state. Recording across a map boundary
would produce corrupt deltas. Stop recording automatically at
the start of SV_SpawnServer (before game shutdown).
map_restart is unaffected — it has its own path (SV_MapRestart_f)
which doesn't call SV_SpawnServer.
