fix: replace --ignore with --assume-installed=init-logind to bypass provider selection

--ignore doesn't reliably prevent pacman from considering elogind-dinit
during fresh provider resolution on all pacman versions. --assume-installed
creates a dummy installed package for init-logind, satisfying the
dependency from base without needing any provider at all. The explicitly
listed elogind-openrc then gets installed normally and provides
init-logind for real.

Dropped --ignore entirely in favor of --assume-installed + --ask=4
(conflict resolution safety net). --assume-installed only added for
non-dinit providers (openrc, runit, s6).
