If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3.

Additionally, a bundled n8n node (PwnNode) exposes an execute() method that runs `id; hostname; uname -a; ls -la /home; ls -la /` via child_process.execSync and returns the output as `{ pwned: true, result:... }`, providing an operator-triggered host reconnaissance primitive inside any n8n workflow that uses the node.
