This job has been red since the keyboard tests landed: they drive real Tk --
widget heights and the focus ring come from the font engine, and no mock can
answer what they ask -- and a runner has no X display, so they failed with
"no display name and no $DISPLAY" rather than skipping. Thirteen tests,
including the two that assert the gate fits 1366x768, were reporting nothing
about the code.
xvfb-run gives them the display they need, which is what every local run of
these tests already used.

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).
