anti f2b3393669 chore: relicense to AGPL-3.0-or-later and add SPDX headers
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.

- LICENSE: full AGPL-3.0 text (gnu.org/licenses/agpl-3.0.txt)
- COPYRIGHT: project copyright notice
- tools/add_spdx_headers.py: idempotent header injector
  (shebang- and PEP 263-aware)

Touches 1565 source files (.py, .ts, .tsx, .js, .jsx, .css, .sh).
No behavior change; comments only.

"""DECNET ServiceBus — pub/sub notification substrate.
The bus is the notification layer for DECNET's worker constellation. The DB
remains the source of truth for anything durable; the bus carries "something
happened, go look" events. Delivery is at-most-once, fire-and-forget.
Consumers call :func:`get_bus` from :mod:`decnet.bus.factory`; never import
transport implementations directly. The factory selects the backend via
``DECNET_BUS_TYPE`` (``nats`` or ``fake``) and honors ``DECNET_BUS_ENABLED``.
Topic hierarchy is defined in :mod:`decnet.bus.topics` and locked early so
consumers can subscribe with stable wildcard patterns.
