Instrument index and scatter stages with `tracing::info` to log input file paths for better runtime observability. Additionally, optimize the path iterator by replacing redundant `is_dir()` checks with explicit `is_file()` validation and deferring metadata resolution, eliminating unnecessary `stat()` syscalls and improving traversal performance on high-latency network filesystems like Lustre and NFS.
