* perf(epic): keep the hidden launcher from loading its store and Fab pages, and compress it while games run The hidden Epic Games Launcher that stays up for sign-in while a game runs pre-warmed its store and Fab pages on a display nobody sees. Under FEX each page used about one core and grew past a gigabyte, crashing and reloading in a loop. The hidden instance now skips the store pre-warm, gets a blank page in place of Fab, and is paged out to zRAM with the Steam client once a game has focus. The visible launcher is unchanged. * test(zram): keep the scan fixture PIDs above the kernel PID range
