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.

"""Step D.0: per-command error-signal helper.

The helper is infrastructure (no primitive emit) — these tests pin
|

``Command.errored`` and ``Command.output_bytes`` semantics directly via
|
||
``build_session_context``. The Phase D primitives (D.1, D.5–D.7) all
|
||
read the same fields, so any drift here breaks four downstream

primitives at once.
