Replaces LICENSE (GPLv3 -> AGPLv3) and prepends
`SPDX-License-Identifier: AGPL-3.0-or-later` to every source file

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.
Sends four crafted stimuli (UDP/closed-port, TTL=1, DF+oversized,
bad IP option) and records which ICMP error classes come back, the
per-error RTT, and the bytes echoed in each ICMP body. Absence is
as informative as a reply — Linux rate-limiting is a fingerprint signal.
Returns None when no packets could be sent (no CAP_NET_RAW), so the
probe is a no-op in non-root test environments. Port-free ActiveProbe
subclass (priority=850), metaclass auto-registered in the registry.
Also fixes three sets of stale tests left over from the TlsCertProbe
migration (4b2759e0):
- test_active_probe_registry: closed name/order sets updated for
tls_certificate and icmp_error
- test_prober_rotation: dead patches on worker.fetch_leaf_cert removed
- test_prober_worker (TestProbeCycleTLSCert): rewritten to test
TlsCertProbe as an independent registry probe, patch target updated
from worker.fetch_leaf_cert to probes.tlscert_probe.fetch_leaf_cert
ActiveProbe.run/syslog_fields/publish_payload now accept port=None so
non-port-iterating probes can live in the registry. Ipv6LeakProbe replaces
the hand-rolled _ipv6_leak_phase special case in worker.py; it runs last
via priority=999. _probe_cycle no longer has an ad-hoc phase call.
Fixes three stale test files (test_prober_bus, test_prober_rotation,
test_prober_worker) that were broken since the 916b21b6 registry refactor.
Replace _jarm_phase / _hassh_phase / _tcpfp_phase boilerplate (3×~50
lines of identical port-iteration logic) with a metaclass-registered ABC.
Adding a new port-iterating active probe is now one class + three methods.
- decnet/prober/base.py: ActiveProbeMeta auto-registers subclasses by
probe_name; ActiveProbe ABC enforces run/syslog_fields/publish_payload
with env-driven DECNET_PROBE_PORTS_<NAME> port override.
- decnet/prober/probes/{jarm,hassh,tcpfp}.py: concrete probe classes.
- decnet/prober/worker.py: single _run_probe driver replaces the three
phase functions; _probe_cycle iterates ActiveProbeMeta.all(); drops
the ports=/ssh_ports=/tcpfp_ports= kwargs from prober_worker.
- IPv6 leak and TLS cert capture stay as special cases (different call
shapes; intentionally outside the registry).
- tests/prober/test_active_probe_registry.py: registry contents, sort
order, priority-10 override, ABC contract per probe class.
- tests/prober/test_run_probe_driver.py: dedup, success, None-skip,
exception, rotation, publish paths for _run_probe.
- tests/prober/test_prober_worker.py: updated patch targets and
_probe_cycle call sites; port control via monkeypatch.setattr.
