Prompts and log lines now follow the user's LANG. Reuses pacman's
gettext catalog for strings with matching upstream msgids
(Proceed with installation?, [Y/n], Starting full system upgrade...,
Do you want to remove these packages?). Moonarch-specific strings
go through an inline _t "en" "de" helper keyed off ${LANG%%.*}.
confirm() switches to pacman-style: :: prefix, default Y, accepts
y/Y/j/J. No PKGBUILD change — gettext ships with base.
Simplified updater that reads package lists from /usr/share/moonarch/
instead of syncing a git repo. Designed to be shipped by the
moonarch-git package as /usr/bin/moonarch-update.
