However, "git-fsck(1)" will check the refs of worktrees. As we decide to get feature parity with "git-fsck(1)", we need to set up support for multiple worktrees. Because each worktree has its own specific refs, instead of just showing the users "refs/worktree/foo", we need to display the full name such as "worktrees//refs/worktree/foo". So we should know the id of the worktree to get the full name. Add a new parameter "struct worktree *" for "refs-internal.h::fsck_fn". Then change the related functions to follow this new interface. The "packed-refs" only exists in the main worktree, so we should only check "packed-refs" in the main worktree. Use "is_main_worktree" method to skip checking "packed-refs" in "packed_fsck" function. Then, enhance the "files-backend.c::files_fsck_refs_dir" function to add "worktree//" prefix when we are not in the main worktree. Last, add a new test to check the refname when there are multiple worktrees to exercise the code.
