Replaces LICENSE (GPLv3 -> AGPLv3) and prepends
`SPDX-License-Identifier: AGPL-3.0-or-later` to every source file
across decnet/, decnet_web/, tests/, scripts/, and tools/.
Rationale: closes the GPLv3 ASP loophole so any party operating a
modified DECNET as a network service must offer their modified
source. Personal copyright (Samuel Paschuan) + inbound=outbound
contributions make a future unilateral relicense infeasible.

Touches 1565 source files (.py, .ts, .tsx, .js, .jsx, .css, .sh).
No behavior change; comments only.
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.
