Every decnet-*.service.j2 hardcoded User=decnet / Group=decnet. The
init CLI accepted --user / --group and used them for useradd,
chown, /etc/decnet ownership and ReadWritePaths — but the Jinja
context omitted them entirely, so
sudo decnet init --install-dir $PWD --user anti --group anti
rendered
User=decnet
Group=decnet
into every unit, which at best ran the workers as a user that didn't
match the files (fails to read the venv / config), and at worst spun
a parallel system user the operator never asked for.
Swap the hardcoded lines to {{ user }} / {{ group }} across all 13
templates and add both to the Jinja context in _install_units.
