Cobra a3c9353d3a Add false positive suppression to net_alerter — fix for #467
- Infrastructure IPs (gateway, self, broadcast) silently ignored in
  on_arrival() and on_departure(); seeded at startup from 'ip route'
- 15-minute departure debounce: alert only fires if device is still
  absent after 900s, eliminating ARP cache flush false positives
- 5-minute re-arrival suppression: ARRIVED alert skipped when device
  returns within 5 min of a recorded departure (covers interface flap)
- DHCP renewal dedup: known device re-announcing within 30 min skips
  ARRIVED alert
- Tests added for all four suppression paths (9 total, all passing)
