dsh-maestro-remote: DSH Remote Access and Tunnel Management Plugin

`dsh-maestro-remote` is a plugin that provides remote access capabilities for DeepSeek Harness. It uses Cloudflare Tunnel to expose local services to the public internet, supports PIN-based authentication to protect the proxy entry point, and allows receiving Webhooks from services such as GitLab. The plugin offers features including tunnel lifecycle management, automatic download of `cloudflared`, traffic distribution, and configuration reloading. Configuration is managed through a shared namespace, and the plugin depends on a Node.js environment. It is designed to address the limitation of local sessions being inaccessible from external systems or unable to receive externally triggered requests.
