feat: community standards, AI moderator, SDDM switch, and README fix

so github told me my repo has NO community standards apparently
CODE_OF_CONDUCT? nonexistent. ISSUE_TEMPLATES? nada.
PULL_REQUEST_TEMPLATE? the void stared back.
and github profiles has a little checklist like im some
kind of degenerate who doesnt know how to run a project.

well NOW i have standards. and they are ROCK SOLID STABLE.
you want systemd? fork from before-systemd-change and figure
it out yourself, i gave you a numbered tutorial right in the
CoC. the AI moderator will read it and then politely but
firmly tell you to go fork yourself (the repo, not literally,
read the CoC).

also threw in the pixie SDDM switch that i apparently never
committed to the netinstall yamls either (kill me), the batch
install main.py cleanup, and fixed the README lying about
why artix.

DEUS VULT and please file your issues in the YAML forms
provided or the AI will judge you
