dsh-vpn-ops: Secure WireGuard and VLESS Reality Operations Plugin for DeepSeek Harness

`dsh-vpn-ops` is a security plugin designed specifically for the DeepSeek Harness to address VPN configuration management when Shell commands cannot be executed in the environment. Through strict authentication and key streaming mechanisms, it securely supports the deployment of WireGuard and VLESS Reality. It provides end-to-end operations across prechecks, plan generation, application, rollback, and client export, with remote changes disabled by default to ensure security. Before deployment, you must confirm that the target server is Debian/Ubuntu and has root privileges, and it is recommended to use a dedicated pre-production server for acceptance testing in production environments.
