Krzysztof kuhy Rudnicki fcd3f7ed2f perf(idle-off): replace controller-watch fork storm with a single systemd-inhibit
turn_off_auto_idle_screen_shutdown.sh --watch-controller forked 4 xset +
1 xdotool per joystick event (blocking on a dd read, debounced by sleep
0.3) — ~21 procs/s while a controller was connected during gaming. The
xset poking was redundant: startup already disables DPMS/blanking.

Replace reset_idle_activity / watch_js_device / the polling watcher with
one long-lived `systemd-inhibit --what=idle:sleep` held only while a
/dev/input/js* device is present, re-evaluated on udev input add/remove
events (event-driven; 30s presence-poll fallback). EXIT+INT/TERM traps
release the inhibitor on every termination path.

Verified live: subtree stays {systemd-inhibit, udevadm} with zero
dd/xset/xdotool; exactly one inhibitor held; clean release on SIGTERM,
no orphans. Takes that loop from ~21 forks/s to 0.

Behavior change: keeps the session awake while a controller is connected
(not only during active input).
