ai-gen-ai-opt-in@99.0.0

ai-gen-ai-opt-in@99.0.0 declares a postinstall hook (postinstall.js) that runs automatically on npm install. The script collects the installer's hostname (os.hostname()), OS username (os.userInfo().username), and public IP/geo/ISP data (fetched from ip-api.com over HTTPS), then encodes those values and issues a DNS lookup for a subdomain of an attacker-controlled Burp Collaborator-style callback host (p1r2d74iwjk057raam6myf7e258wzkt8i.oastify.com). This is a covert out-of-band DNS exfiltration channel that leaks installer identity and location data to a third party on every install, with no legitimate documented purpose.
