How do I remediate sq-minimal-feature-flags if I installed it?

Remove sq-minimal-feature-flags from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound activity or persistence.

I already installed sq-minimal-feature-flags — how do I know if it already compromised me?
