Two single-use scripts with no deployed copy, so the entry+lib shape is
safe. Each keeps the ordering, the safety checks and the user-facing output;
the configuration writers move to a library beside it.
Both scripts write `set -e # Exit on any error`, so extract_shell_functions.py
now matches the directive rather than the whole line. Regression-checked by
re-deriving the committed fresh-install/main.sh split byte-for-byte.
Verified: all 6 and all 9 top-level functions verbatim via the shfmt
harness; both libraries source with no side effects and define every
function moved into them; bash -n passes on all four.
Neither script was run. nvidia_troubleshoot.sh writes /etc/X11 config and
installs pyroveil; setup_passwordless_system.sh writes sudoers and lightdm
autologin, which is what this machine's login depends on.
Over-cap files 31 -> 29.

- 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
