fix(deploy): override packages target home-relative paths

zz-<host> packages nest base-package dirs internally (zz-blankpad/niri/.config/...);
stripping only the package prefix yielded targets like $HOME/niri/.config/... .
Strip the nested package segment for zz-* packages so overrides land on the
same home-relative target as the base copy they override.
