When .git already existed on EFS, git fetch + reset --hard FETCH_HEAD updated the working tree but left HEAD pointing to the original branch (e.g. master). Added git checkout -B to update HEAD to the correct target branch.
When .git already existed on EFS, git fetch + reset --hard FETCH_HEAD updated the working tree but left HEAD pointing to the original branch (e.g. master instead of release/20260408). Now reads .git/HEAD via read_local_file and runs git checkout -B only when the branch actually changed, avoiding unnecessary work when the branch is the same.
