Flathub's recent ban on AI-using projects (see #6724) puts Lutris's Flatpak channel at risk, and Flatpak has always been an awkward fit anyway: Lutris is fundamentally an unsandboxed game manager that needs to call host xrandr, 7z, fuser, wine, flatpak, mount drives, and reach the user's whole $HOME. AppImage gives us a single-file distribution that does none of that sandboxing. This adds `make appimage`, which builds a self-contained AppImage in a Docker/Podman container based on Ubuntu 22.04 (glibc 2.35, Python 3.10, GTK3, WebKit2GTK 4.1). The pipeline: utils/appimage/build.sh — host wrapper (docker or podman) utils/appimage/Dockerfile — build env with all GI typelibs utils/appimage/build-in-container.sh — assembles AppDir via linuxdeploy + linuxdeploy-plugin-gtk, runs appimagetool utils/appimage/AppRun — launcher; sources plugin-gtk hook, sets PYTHONPATH, execs bundled python3 with bin/lutris Design notes worth flagging for review: * The bundled Python is the build image's /usr/bin/python3.10 plus its stdlib, with tkinter/test/idle stripped. * PyGObject and dbus-python are taken from apt (python3-gi, python3-dbus) rather than pip — both have switched to meson-python build backends that drag in a sizeable toolchain, and the prebuilt packages link against exactly the libgirepository/libdbus we already bundle from the same distro. * AppRun deliberately does NOT export LD_LIBRARY_PATH. linuxdeploy already sets $ORIGIN-relative RPATH on every binary it deploys, and exporting LD_LIBRARY_PATH would leak into every host subprocess — which surfaced immediately when flatpak crashed loading our bundled libssl 3.0 instead of the host's 3.4. The build script patchelf's the RPATH on the manually-copied _gi.so / _dbus*.so so they still find the bundled libgirepository without the env override. * PATH is left intact apart from prepending $APPDIR/usr/bin, so host tools (xrandr, 7z, wine, flatpak) still win — that's the whole point of choosing AppImage over Flatpak here. Output is dist/Lutris-<version>-x86_64.AppImage at ~83 MB. Smoke-tested end-to-end on Fedora 43 Nobara: boots GUI, GPU detection, DB load, service auth, GTK theme, and host subprocess invocations all work. Refs #6724.
