Hello,
Thank you for your great work
here is a bug I encountered

What did you do before the bug happened? (Steps to reproduce your issue)
#!/bin/bash

mkdir topfolder
cd topfolder
mkdir main-worktree
cd main-worktree
git init
mkdir dir
touch file-a dir/file-b
git add .
git commit -m "Initial commit":

cat >.git/hooks/cd-bug << EOF
#!/bin/bash

echo -e "\n\nrunning cd-bug hook"
# Redirect output to stderr.
exec 1>&2

echo "<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<"
git describe
echo pwd : $(pwd)
echo pwd_var : $PWD
echo git_prefix: $GIT_PREFIX
echo git_dir: $GIT_DIR
echo git_work_tree: $GIT_WORK_TREE
git status
echo "========================================================"
cd dir
echo pwd : $(pwd)
echo pwd_var : $PWD
echo git_prefix: $GIT_PREFIX
echo git_dir: $GIT_DIR
echo git_work_tree: $GIT_WORK_TREE
git status
echo ">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>"
echo -e "cd-bug hook done\n\n"

EOF
chmod u+x .git/hooks/cd-bug

# behave as expected
git hook run cd-bug

git branch branch_b
git worktree add ../second-worktree branch_b
cd ../second-worktree

# broken behaviour here
git hook run cd-bug

# end of script



What did you expect to happen? (Expected behavior)
On branch branch_b
nothing to commit, working tree clean


What happened instead? (Actual behavior)
On branch branch_b
Changes not staged for commit:
  (use "git add/rm <file>..." to update what will be committed)
  (use "git restore <file>..." to discard changes in working directory)
        deleted:    dir/file-b
        deleted:    file-a

Untracked files:
  (use "git add <file>..." to include in what will be committed)
        file-b


What's different between what you expected and what actually happened?
-> Running `git status` after `cd` in a pre-commit hook lists all
repo's tracked file as deleted.
   However when running the hook from the main-worktree, I have no issue.

   In my final use case, I'm doing something that goes like below
   cd subfolder
   `git stash --keep-index`
   `./update-generated-files` which updates some files in subfolder
and subfolder/*/
   `git stash pop`
