Patches and extra sources

Files Steamify builds or applies, kept out of the shell code so they can be read and reviewed on their own. lib/*.sh reads them with patch_file <name> (piped through fill KEY=value... for @KEY@ placeholders); the single-file build (.github/tools/bundle.sh) embeds them.

File	Used by	What
steamify-fremont-poweroff.c	lib/fremont-poweroff.sh (Steam Machine support)	Kernel module (DKMS): clears GPIO 18's S4/S5 wake bit before power-off, so the Steam Machine stays off with recent kernels
sync-steamos-session.sh	lib/login-manager.sh (SteamOS conversion, plasma-login-manager)	The sync bridge: copies Steam's session choice from zz-steamos-autologin.conf into plasmalogin.conf's [Autologin]
ensure-kernel-headers.sh	lib/steam-machine.sh (Steam Machine support)	Run at boot: installs missing headers for every installed kernel
leds-valve-dkms.conf	lib/steam-machine.sh (Steam Machine support)	/etc/dkms override: build the LED driver for DKMS's target kernel; appended to someone's own override, which is backed up and restored
steamify-fremont-poweroff.dkms.conf, steamify-cros-ec-cec.dkms.conf	lib/fremont-poweroff.sh, lib/cec.sh	The DKMS modules' dkms.conf (fill NAME=... VERSION=...)
steam-shortcuts.py	lib/steam-game.sh (Add as non-Steam game)	Reads and writes Steam's binary shortcuts.vdf (find, add or update, remove)
steamify-notifier.py	lib/update-notifier.sh (Update notifications)	The daily check: notification and tray icon when there's a new release
steamify-os-release.sh, steamify-os-release.hook	lib/login-manager.sh (SteamOS conversion)	What Steam's System settings show besides the OS name (which stays CachyOS's): VERSION_ID=steamos-X.Y, VERSION_CODENAME=steam-machine, VARIANT/VARIANT_ID Steamify with its version, in /etc/os-release; the pacman hook runs it again after cachyos-hooks (fill SCRIPT=... VERSION=... STEAMOS=...)
steamify-nvidia-initramfs.sh, steamify-nvidia-initramfs.hook	lib/nvidia.sh (SteamOS conversion, NVIDIA fix)	The pacman hook (before the initramfs is built, after DKMS) and its script: the NVIDIA modules go into the initramfs only while every installed kernel has them, decided again at every kernel or driver change (fill SCRIPT=...)
cros-ec-cec-single-port.patch	lib/cec.sh (HDMI-CEC)	Makes Valve's Steam Machine CEC driver find amdgpu's HDMI port
