- linux_configuration/tests: update script paths after periodic_background/
reorganisation (hosts_file_monitor, makepkg_capped, music_parallelism,
shutdown_timer_monitor, usage_monitoring_installer_efficiency)
- test_i3blocks_efficiency.sh: remove checks for HEARTBEAT_INTERVAL_S and
WARP_POLL_INTERVAL_S constants that no longer exist
- test_pacman_wrapper_security.sh: remove tests 20-21 (builtin time helpers /
external date calls) that are no longer applicable; update path
- generate_hosts_file.sh: add sed unblock rules for delio.com.pl and
loverslab.com to stay consistent with install.sh whitelist
- steam_backlog_enforcer/scanning.py: remove unplayable_reason arg from
logger.info call (too many format args); drop matching test assertion
- steam_backlog_enforcer/tests/test_protondb.py: add
test_unplayable_reason_no_trending_tier to restore 100% branch coverage
on protondb.py line 97 (was previously covered indirectly)
- 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
