Delete a contact.

Deletion operations cannot be undone and result in permanent data loss. This is classified as Destructive rather than Write because the action is irreversible. Severity is high because contact deletion affects user data management and could disrupt communications if contacts are removed unintentionally. High confidence due to explicit 'delete' terminology.
