anti 010568e558 feat(asn): IP→ASN enrichment via iptoasn.com bulk dump
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.
