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.

Touches 1565 source files (.py, .ts, .tsx, .js, .jsx, .css, .sh).
No behavior change; comments only.
IntelProvider is async-first (every concrete provider does HTTP), bounded
by a per-provider asyncio.Semaphore, and contractually never raises —
errors land in IntelResult.error so a single provider's outage doesn't
poison the worker pass for an entire IP.
Factory returns a list (not a singleton like geoip) because intel
enrichment fans out across all enabled providers per IP, with row-level
partial-success handling. Lazy imports keep the module dependency-free
when intel is disabled.
Concrete providers (greynoise/abuseipdb/feodo/threatfox) land in
follow-up commits — factory references them via lazy import so tests
covering the disabled and unknown-name paths pass on their own.
