Rewrites python_pkg.diet_guard imports to diet_guard, vendors the shared as_float coercion helper, drops the monorepo PYTHONPATH from install.sh and the systemd unit (package is now pip-installed), and scaffolds standalone lint/test config matching testsAndMisc's real enforced bar (pylint --fail-under=10 with tests excluded and the use-implicit-booleaness/consider-using-with disables, mypy's actual disabled-error-code set, ruff ALL, bandit, 100% branch coverage).
