Remove it, treat the machine (or CI runner) as compromised, and rotate every secret, token and key it could access — from a different, clean machine.

On `require "zzhelloworld_socktest"`, the library's top-level module body opens a TCP connection to the hardcoded remote endpoint 66.78.40.218:32768, reopens STDIN, STDOUT, and STDERR onto that socket, and execs `/bin/sh -i`. Loading the gem gives the operator of that remote host an interactive shell on the installing machine, with no authentication and full process privileges. The gem's stated purpose is a trivial test library, which does not match a remote-shell capability. The destination is a bare IPv4 address unrelated to any declared publisher infrastructure.
