anti aa833ddda9 feat(sniffer): passive IPv6 link-local leak detection ...

Add _ipv6_iid_classify() to fingerprint EUI-64 vs stable-privacy IIDs
and derive the MAC OUI from EUI-64-encoded link-local addresses.
SnifferEngine._on_ipv6_packet() observes fe80::/10 sources destined for
known deckies and emits ipv6_link_local_leak syslog + bus events.
on_packet() now dispatches the IPv6 branch before the v4 TCP path.
BPF default widened from "tcp" to "tcp or ip6" so the sniff loop
captures IPv6 frames without config change.
