pre-commit hook sets GIT_INDEX_FILE to this "index.lock" so you have
the latest index content (which is not the same as from
$GIT_DIR/index). This variable will interfere with any commands that
work on a different worktree.
So you probably can still make it work by backing up $GIT_INDEX_FILE
(in case you need it), then unset it before you use "git worktree" (or
cd to it if you keep a permanent separate worktree for pre-commit
activities). To make sure you don't have similar problems, you
probably should do "env | grep GIT" from the hook and see if any other
variables are set.
