omdsh-remctrl: Adding a Remote Access Entry Point to DeepSeek Harness

`omdsh-remctrl` is a remote control plugin for DeepSeek Harness, designed to address the inconvenience of operating from mobile devices. By using a reverse proxy and a Cloudflared tunnel, it exposes the full DSH interface to the public internet, allowing users to view sessions, approve requests, and assign tasks from a phone. Core features include HTTP/WebSocket forwarding, password authentication, automatic tunnel generation, and mobile optimization. The plugin is disabled by default and must be manually enabled in the Plugin Center. Security relies on DSH’s session mechanism and rate limiting. Installation requires a Node.js environment, involves minimal configuration options, and supports using either the default Cloudflare tunnel address or a custom domain.
