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.
Synthesize the covering CIDR at lookup time from the matched iptoasn
range using ipaddress.summarize_address_range. AsnInfo.prefix is
populated per-query; not persisted in the pickle cache.
enrich_ip now returns (asn, as_name, bgp_prefix, provider_name).
Profiler worker updated to unpack the 4-tuple and write bgp_prefix
into the attacker record dict.
Adds asn (int), as_name (varchar 128), asn_source (varchar 16) to
the Attacker SQLModel — direct columns, no _migrate_* helper per
feedback_no_new_migrations_prev1.
Profiler worker now calls decnet.asn.enrich_ip alongside the existing
geoip enrich_ip; both feed the upsert payload. Failure is total — if
either lookup throws or the IP is private/unannounced, the field stays
None and the row still writes.
Both lookups are independent: a CGNAT address can have a country (RIR
allocation) but no ASN (no BGP origin), and vice-versa for unrouted
RIR-allocated space. Storing them separately preserves that signal.
Mirrors decnet/geoip/ end-to-end: paths/base/factory/lookup at the
package level, iptoasn/ subpackage holds the data-source-specific
fetch+parse+provider. AsnLookup is bisect-indexed over (start, end,
AsnInfo) ranges with a pickled cache invalidated on raw-file mtime
bump.
Why iptoasn (and not bgp.tools / Team Cymru): public-domain dump,
zero attribution, no UA mandate, daily refresh — keeps DECNET stealth
intact (the geoip/rir module's "never identify as DECNET" comment
applies the same way here). bgp.tools' ToS would have required an
identifying UA, conflicting with feedback_stealth.
Public surface: decnet.asn.enrich_ip(ip) -> (asn, name, source) or
all-None on miss/disabled. Same shape as decnet.geoip.enrich_ip so
the profiler can compose them in one call site.
