- 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
