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.

No behavior change; comments only.
Two reusable bundle-derived lookups that the next two commits build
on:
- mitre_url_for(tid) returns the canonical attack.mitre.org URL by
reading external_references on the cached attack-pattern. Backed
by the existing lru-cached _attack_pattern_by_id so per-call cost
is constant. Handles top-level techniques and sub-techniques
(T1059.004 -> .../techniques/T1059/004).
- GroupRef + groups_using_technique(tid) surface the intrusion-set
reverse index from the loaded bundle: given a technique, return
the MITRE-tracked groups documented as using it. Sorted by
group_id for deterministic responses; lru-cached. Sub-technique
semantics match ATT&CK Navigator (do NOT auto-union with parent).
- decnet/ttp/data/intel_loader._mitre_url_for collapses to a thin
re-export of attack_stix.mitre_url_for; the loader keeps mitre_url
on TechniqueEmission for the eventual STIX export.
- tests/ttp/test_attack_url.py covers both helpers: top-level + sub
URLs, unknown -> None / (), GroupRef immutability + hashability,
deterministic ordering, sub-technique distinct from parent.
