The first -n auto Tests run segfaulted in Tk's focus_force(): keyboard
focus is global to an X display, and four workers were sharing the one
xvfb-run display, stealing each other's focus. Stressed locally (layout +
keyboard tests x40, -n 8): 5 of 2760 failed on a shared display (focus-ring
assertions), 0 of 4600 with pytest-xvfb's per-process display -- and faster.
The geometry xvfb-run used moves into pyproject; the workflow keeps the
Xvfb install guard and drops xvfb-run.

pre-commit took ~119 s as one job (24 s of pip, then every hook env and
every hook in series); Tests took ~56 s (26 s of pip, 7 s of apt-get for an
xvfb the image already ships, 17 s of -v pytest). Same hooks, same flags,
same 100% bar -- just parallel runners, cached uv wheels, xdist workers.

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).
