Cobra 52fc12b97a Fix false presence: only trigger arrival on NUD_REACHABLE, not STALE/DELAY/PROBE
Kernel fires RTM_NEWNEIGH for NUD_STALE, NUD_DELAY, and NUD_PROBE states
as it probes a potentially-departed device. Each probe was calling on_arrival()
which refreshed last_seen, preventing the watchdog from ever detecting departure.

Only NUD_REACHABLE confirms a device is actually on the network.
