Single-writer controller with a select loop that offers jobs and accepts results simultaneously, so bounded channels cannot deadlock. statx/fstatat relative to the directory fd on Linux/macOS, portable fallback elsewhere. Hard links counted once, symlink loops detected, virtual filesystems skipped, errors classified and surfaced.
