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).

- Move all linux_configuration scripts into two semantic categories:
- single_use/: scripts run once manually (fresh install, fixes, setup)
- periodic_background/: scripts run by systemd timers or daemons
- Preserve existing subdirectory structure within each category
- Fix lib/common.sh source paths for new directory depths
- Fix CONFIG_DIR depth in setup_periodic_system.sh and check_and_enable_services.sh
- Update all references in tests, fresh-install/main.sh, nix modules, and docs
- Fix check_polling_antipatterns.sh false positives (||, regex |, case patterns, jq strings)
- Fix pre-existing mypy exclusion path and type annotations for moved tools/ directory
- Rewrite check_polling_antipatterns.sh using awk (no bash regex loops); add require_serial: true
