dsh-guard-messenger: Securely Expose DeepSeek Harness via Telegram/Discord

The DeepSeek Harness (DSH) plugin `dsh-guard-messenger` uses Cloudflare Quick Tunnel to provide secure remote access to a local Harness instance from a mobile device. It leverages an edge connection to forward traffic to the local `127.0.0.1` address without exposing local ports. The plugin supports one-click toggling via Telegram or Discord and offers passwordless access to a Web UI along with Agent runtime capabilities. While it reduces the attack surface, users should note that TLS terminates at the edge, no SLA is provided, and prompt injection risks remain. Developers should protect the source code and rotate keys promptly if a key leak occurs.
