Drop GeoLite2-ASN.mmdb dependency (required license key) in favor of
iptoasn.com ip2asn-v4.tsv (no auth, public domain). Bisect-based
lookup in pure stdlib, downloaded via SOCKS5 in update-data.sh.
Adds 30 test cases covering load, lookup, and command handler.

GeoIP and ASN lookup via MaxMind GeoLite2 mmdb, Tor exit node check
against local bulk exit list, IP reputation via Firehol/ET blocklist
feeds, and CVE lookup against local NVD JSON mirror.
Includes cron-friendly update script (scripts/update-data.sh) for all
data sources and make update-data target. GeoLite2 requires a free
MaxMind license key; all other sources are freely downloadable.
