If this package is installed

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.

Details

Runs on install. The preinstall script sends the output of `id` (the installing user's identity and groups), base64-encoded, to a request-bin host with curl. This is the dependency-confusion probe pattern; it leaks data from every machine that installs the package.
