ls: prevent ReadDir from closing before entries are processed The issue occurred because ReadDir was being consumed by the for loop, causing it to be dropped immediately after iteration. This closed the directory file descriptor (FD 3) before metadata() could be called on the entries, since /proc/self/fd shows the process's own open FDs. By using read_dir.by_ref() in the loop, we borrow the iterator instead of consuming it, keeping the ReadDir (and its underlying FD) alive until enter_directory() completes. Fixes: #9332
