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.
Reject symlinks, hardlinks, device nodes and FIFOs in update tarballs;
validate each member's resolved path stays under dest after symlink
resolution; cap uncompressed size at 256 MiB to bound gzip-bomb damage;
strip setuid/setgid bits from extracted modes.
Add an optional sha256 form field to /update and /update-self; the
master client computes and sends it on every push, the executor
refuses to extract on mismatch. mTLS already authenticates the
master, so this is defence-in-depth against in-transit corruption
and gives operators a way to pin "exactly these bytes" for vetted
releases.
All three workers now share a run_health_heartbeat helper in
decnet.bus.publish. Each publishes system.<worker>.health on a 30s tick
with {worker, ts} plus optional per-worker extras. Subscribers can
watch system.*.health to see every DECNET worker on a host at once.
- agent: heartbeat runs inside the FastAPI lifespan alongside the
existing master-facing heartbeat; bus-disabled path is a no-op.
- forwarder: heartbeat task spawned at run_forwarder entry, cancelled
in the finally block so a crashed master loop never leaks the task.
- updater: new FastAPI lifespan hosts the heartbeat.
Heartbeat helper swallows extra() failures and is cancellation-safe so
lifespan teardown never hangs on it.
Adds a separate `decnet updater` daemon on each worker that owns the
agent's release directory and installs tarball pushes from the master
over mTLS. A normal `/update` never touches the updater itself, so the
updater is always a known-good rescuer if a bad agent push breaks
/health — the rotation is reversed and the agent restarted against the
previous release. `POST /update-self` handles updater upgrades
explicitly (no auto-rollback).
- decnet/updater/: executor, FastAPI app, uvicorn launcher
- decnet/swarm/updater_client.py, tar_tree.py: master-side push
- cli: `decnet updater`, `decnet swarm update [--host|--all]
[--include-self] [--dry-run]`, `--updater` on `swarm enroll`
- enrollment API issues a second cert (CN=updater@<host>) signed by the
same CA; SwarmHost records updater_cert_fingerprint
- tests: executor, app, CLI, tar tree, enroll-with-updater (37 new)
