Also thread metadata through the ignore_file -> build_node boundary so filter-active walks (-x / -M / -A / -y) stat each entry at most once. Correctness verified by diffing output against the pre-change binary with default flags, -i, -e, -v, -X, -M, -x. Assisted-by: Claude Opus 4.7 (code review, refactoring)
Under `-f` the file's stat is mostly thrown away — `node_from_tuple` sets size to 1 and the time fields are only read when -M/-A/-y are on. The only field still needed downstream is `inode_device` for `clean_inodes` dedup, and both halves are syscall-free: `inode` from `DirEntry::ino()` (getdents64), `dev` from the parent directory's cached tuple. Gated to `-f` without `-L` and without metadata-needing filters, so output is byte-identical to the previous stat path. Unix-only; Windows DirEntry has no cheap d_ino analogue.

Syscall reduction verified via strace on a 3-dir / 5-file test tree: statx count drops from 11 to 8, exactly one per directory saved. Assisted-by: Claude Opus 4.7 (code review, refactoring)
