Every version was published to cause harm.\n\nTask:\n1. Search this repository's dependency manifests and lockfiles for the package, including transitive dependencies.\n2. If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4.

The use of detached/no-window flags hides this from the user, and the README advertises only ML notebook code generation — the destructive behavior is undisclosed. This is install/use-time destruction of installer-side resources: open terminal sessions are force-killed (causing loss of unsaved work in any other shell the user has open) and the package removes itself behind the user's back.
