chelsealong d6b036b726 fix(state): compare fd identity against the watched path, not st_nlink
st_nlink == 0 alone cannot distinguish a genuine orphan from one that
still has a surviving hard link (e.g. a backup) after the watched
sidecar path itself was removed or replaced — that left st_nlink >= 1
on a truly orphaned generation, letting a new opener through while a
live writer still owned the old one. Compare (st_dev, st_ino) between
the fd and the current watched sidecar path instead: only an exact
match means they're the same live file, so any mismatch or unstattable
watched path still fails closed.
