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.
E.3.9.0 prerequisite for the per-source lifters (E.3.9-E.3.13). The
dispatch index, install/evict/apply_change atomic-swap protocol, and
state-modulation helpers (is_active / apply_ceiling) move out of
rule_engine.py into _rule_index.py and _state.py. RuleEngine wraps a
RuleIndex; back-compat shims preserve _by_kind / _by_rule / _install
attribute access for tests poking at the dispatch internals.
Lifters in E.3.9-E.3.12 will each hold their own RuleIndex, watching
the same RuleStore via subscribe_changes() fan-out. Hot-reload
semantics (disable / clip / TTL via set_state API) now reach
lifter-bound rules through the same atomic-swap path the engine uses,
not a future composite-rebuild compromise.
