/* Nanosecond-precision lstat for the working-tree walk.
 *
 * V's `os.Stat` exposes mtime and ctime in whole seconds. The file cache in
 * `src/snapshot` decides whether a file may skip hashing by comparing those
 * timestamps, so second precision would let a file edited twice inside one
 * second keep a stale hash — and a save would then record the wrong content.
 * This shim reports nanoseconds, plus the file kind, which the walker needs to
 * skip symlinks and directories without a second stat call.
