R6.6 round 1 fix: no Git says to install ElyTree; Linux keeps Mark's Git

git::own returns git::NoGit when neither the app nor ElyTree has Git;
ElyMark's Git item then reads 'needs ElyTree'. Linux AppImages stand
alone, so ElyMark keeps its Git there (packages share the AppDir).
The bundle fixture now has ElyTree's executable folder.
