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.
Each successful JARM / HASSH / TCPfp probe fans out an
attacker.fingerprinted event; the probe family goes in event.type so a
single subscription covers all three. Payload carries the attacker IP,
port, and probe-specific hash — enough for the MazeNET live map to
render fingerprint info on observed attackers.
Lifts the thread-safe publisher helper out of the sniffer worker into
decnet/bus/publish.py so the prober (and every future worker with a
to_thread hot path) can reuse it without copy-pasting the
run_coroutine_threadsafe dance. Sniffer rewires onto the shared helper
in passing.
Adds ATTACKER_FINGERPRINTED as a new leaf — distinct from
ATTACKER_OBSERVED (correlator's first-sight signal) because an active
probe result is additional evidence about an already-observed attacker.
Note: the plan's decky.{id}.state realism-probe publish path is
deferred — the current prober fingerprints attackers, not decky
realism. Will revisit when realism probes exist.
SnifferEngine gains an optional publish_fn hook, invoked after the
dedup + syslog write for traffic-summary events only (tls_session,
tcp_flow_timing, tcp_syn_fingerprint) — intermediate parser artifacts
like tls_client_hello stay off the bus.
The sniffer worker wires get_bus() + a thread-safe shim that marshals
sync calls from the scapy sniff thread back onto the asyncio loop via
run_coroutine_threadsafe. Bus failure at startup degrades cleanly to
publish-off mode; publish failures at runtime never escape the sniff
thread.
