in the end i understood that there was no magic safe defaults, so i had
to configure an outputs section to enable my screen, which wasnt very
obvious.

SMITHAY_USE_LEGACY wasnt needed, and niri starts fine from greetd, shows
its help screen listing keybindings, i can open a term.. and then it
crashes hard, with a coredump

drop this section from startniri.sh:

if [ ! -d "${XDG_RUNTIME_DIR}" ]; then
    mkdir -m 700 -p "${XDG_RUNTIME_DIR}"
fi

and fix the readme to explain/stress what's the minimal requirements for the
config.. with that the port itself is definitely fine, ok to import, further
improvement can be done in-tree.
