Replace recursive safe_traverse_dir with iterative depth-first search using a stack to prevent file descriptor exhaustion during deep directory hierarchies. Also collect read_dir entries upfront to release the directory iterator early, reducing resource usage.
Use rlimit crate's .limit() method instead of manual libc rlimit calls for constraining NOFILE. This cleans up the test code and leverages existing utilities in the rlimit crate. Additionally, optimize import by using PathBuf directly from std::path.
