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

(shebang- and PEP 263-aware)
Touches 1565 source files (.py, .ts, .tsx, .js, .jsx, .css, .sh).
No behavior change; comments only.
Dispatches by extension: .prof -> snakeviz, memray .bin -> memray flamegraph
(overridable via VIEW=table|tree|stats|summary|leaks), .svg/.html -> xdg-open.
Positional arg can be a file path or a type keyword (cprofile, memray, pyspy,
pyinstrument).
Root cause of 'No python processes found in process <pid>': py-spy needs
per-release ABI knowledge and 0.4.1 (latest PyPI) predates 3.14. Wrapper
now detects the interpreter and points users at pyinstrument/memray/cProfile.
New `profile` optional-deps group, opt-in Pyinstrument ASGI middleware
gated by DECNET_PROFILE_REQUESTS, bench marker + tests/perf/ micro-benchmarks
for repository hot paths, and scripts/profile/ helpers for py-spy/cProfile/memray.
