feat: add redirect-chain blocklist check, tune urlscan polling

[calebephrem]

What does this PR do?

• scan command now resolves a URL's full redirect chain and checks each hop against a local blocklist of known IP logger/grabber domains before running external scans (#44
• also scan command's urlscan.io polling now runs 5 attempts at 3s intervals instead of a 10s wait plus 8x5s polls (#44)
