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.
Mirrors the IP-ID classifier for TCP ISN values: per-source-IP rolling
deque (maxlen=8) populated from each inbound SYN's tcp.seq, classified
on every emission. A 'random' verdict is the modern norm; 'incremental',
'zero', or 'constant' indicates legacy stacks or hand-rolled raw-socket
tooling — a strong fingerprint signal.
Active prober now also captures server_isn (single sample, not classified
in-flight; downstream consumers correlating multi-probe results can apply
seq_class.classify_sequence themselves).
Profiler rollup carries the latest non-'unknown' label into
attacker.tcp_fingerprint. Dedup key already covers isn_class from
the previous commit, so transitions emit cleanly.
UI surfaces ISN class as a colour-coded tag with a ⚠ glyph for
non-random verdicts, since they're the genuinely interesting case.
Active prober now reads ip.tos from the SYN-ACK and emits tos/dscp/ecn
alongside the existing TTL/window/options fields. dscp is folded into the
fingerprint hash so different DSCP markings produce distinct signatures.
Passive sniffer logs the same three fields on tcp_syn_fingerprint events;
profiler rollup carries them into the attacker tcp_fingerprint snapshot;
AttackerDetail's TCP STACK panel now surfaces DSCP and ECN cells.
Groups every flat test_*.py under the module it exercises, matching the
existing tests/{profiler,sniffer,prober,collector,correlation,cli,web,
topology,swarm,bus,updater,api,docker,geoip,...} layout. New folders:
services/, fleet/, config/, logging/, db/ (+ db/mysql/), telemetry/,
mutator/, core/.
Path-dependent __file__ references bumped an extra .parent in three
files that moved one level deeper:
- tests/sniffer/test_sniffer_ja3.py (template path)
- tests/services/test_ssh_capture_emit.py (template path)
- tests/cli/test_mode_gating.py (REPO root)
- tests/web/test_env_lazy_jwt.py (repo var)
Also drops two SQLite runtime artifacts (test_decnet.db-{shm,wal}) that
were leaking into the repo from a previous test run.
Fixes two test_service_isolation cases that patched asyncio.sleep (no
longer on the profiler main-loop hot path — same pre-existing bug I
fixed earlier in test_attacker_worker.py) by patching asyncio.wait_for
and passing interval=0.
