wipe_node
Reset a node to factory state in EVE-NG by deleting all user configuration, including startup-config and VLANs, so the next start rebuilds from the selected image.
Instructions
Wipe a specific node (reset to factory state).
This tool wipes a node, deleting all user configuration including startup-config, VLANs, and other settings. The next start will rebuild the node from the selected image.

Implementation Reference
- The main handler function for the wipe_node MCP tool. It validates input using NodeControlArgs, checks connection, calls the EVENGClientWrapper.wipe_node helper, and formats the response as TextContent.
