enricobuehler	61aa1053e7	feat(host/gamescope): headless game mode that follows the box + matches the client ... Make Steam game mode work on a display-less streaming host and stream it at the client's resolution: * Ship /etc/gamescope-session-plus/sessions.d/steam (packaging/bazzite/ gamescope-headless-session, installed by the RPM + Arch PKGBUILD): fall back to gamescope's headless backend when no display is connected, so "Switch to Game Mode" boots offscreen instead of crashing on the missing panel (and 5-striking back to desktop). No-op on display-attached boxes; only sets unset values so the host's per-client mode still wins. * Default Bazzite/SteamOS to ATTACH (PUNKTFUNK_GAMESCOPE_ATTACH=1 in host.env): the box owns its session (Desktop<->Game, persistent), the host follows + captures it and never tears it down — so switching is rock-solid and a disconnect leaves the box in its mode (reconnect returns there). * Resize-on-attach (gamescope.rs): on connect, ensure the box's own game-mode session runs at the CLIENT's resolution — reuse it when already matching (fast path, no restart), else reconfigure + restart the box's own autologin gamescope-session-plus@<client> at the client mode (cooperative: no competing unit, so no autologin-respawn fight). Detect the live gamescope's -W/-H via argv[0] in /proc (its /proc/<pid>/exe is unreadable for that process). Validated live on a headless bazzite-deck-nvidia box: game mode boots headless + stable (0 strikes); the host attaches + streams video/audio/EIS input; a 5120x1440 client reuses the matching session and streams at 5120x1440.
