raspberry_pi_nextcloud.sh 1276 -> 163, root_bl9000.sh 1116 -> 211,
lookup_docs.sh 942 -> 165. Sixteen new libs.
lookup_python was one 300-line function; its keyword-to-anchor mapping
became python_keyword_doc, emitting result and desc tab-separated so the
caller keeps its control flow.
bl9000_mtkclient had cd X; work; cd - with three return paths.
install_mtkclient became a subshell; extract_boot_with_mtkclient could
not, since it exports BOOT_IMG - so the venv check moved before the cd,
the cd is guarded, and the restores use a saved $PWD.
Four more unguarded cd calls fixed, and a third instance of the lib
chaining bug flattened. lookup_docs.sh had no SCRIPT_DIR at all.

- 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
