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 small observability follow-ups to the phase-1 agent/topology wiring:
TopologySummary now carries needs_resync so operators can see the
heartbeat's resync flag via the topology list/detail API without
dropping into the DB.
TopologyStore.record_error becomes an upsert — when a docker/compose
failure fires during the first materialise (put() never reached), we
still land a marker row so GET /topology/state surfaces the error and
the next heartbeat carries an empty applied_version_hash. That empty
hash is what master's heartbeat check relies on to flag the topology
for resync instead of assuming the apply succeeded.
New mTLS-protected routes on the agent:
- POST /topology/apply — master pushes {hydrated, version_hash}.
Validates the hash matches locally (serialisation drift guard),
runs the topology through the same validator/composer pipeline
used master-side, then creates bridges + compose up + records the
apply in topology.db.
- POST /topology/teardown — dismantles compose, removes bridges,
clears topology.db. Idempotent.
- GET /topology/state — returns applied row + live docker
observation for the heartbeat.
Implementation lives in decnet/agent/topology_ops.py; it reuses the
private compose helpers from decnet.engine.deployer so we don't
duplicate compose/project-name plumbing. The apply path is sync
under the hood (docker SDK + subprocess); we hop to a thread so the
event loop keeps servicing other agent traffic.
v1 is one-topology-per-agent; cross-topology apply returns 409.
Step 4 of the agent <-> topology integration.
