The update-submodules workflow did a full recursive checkout (submodules: recursive, fetch-depth: 0), cloning every submodule's entire contents and history just to read each branch's tip commit. Resolve the tip SHA with 'git ls-remote' instead and update the gitlink directly in the index with 'git update-index --cacheinfo'. No submodule content is downloaded, and the parent checkout is now shallow with submodules disabled. Signed-off-by: Julius Knorr <jus@bitgrid.net>
