Cancel a wizard session and discard its in-memory answers.
AI agents call wizard_cancel to permanently remove resources in Narrarium — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool discards in-memory answers from a wizard session, which is irreversible — any data entered into the wizard is permanently lost. While the blast radius is limited (only in-memory/session data is affected, not persistent storage), the action cannot be undone. This places it in the Destructive category rather than Write.
