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.
Ipv6LeakLifter subscribes to source_kind="ipv6_leak" events from both
the passive sniffer and active prober. Emits T1090 (Proxy) under TA0011
(C2) when fe80:: source address is observed — the attacker's VPN only
tunnels IPv4 so their link-local IID leaks their NIC identity.
Rule R0059 sets base confidence 0.85; iid_kind in the evidence carries
the per-observation strength (eui64 = MAC-derived, deterministic;
stable_privacy = RFC 7217; temporary = RFC 4941).
