dsh-remote-plugin: Integrate DSH Remote Panel and Gateway into DSH

dsh-remote-plugin is the official Bundle plugin for DSH, designed to access remote entry points, status panels, and gateways via a web client. It allows users to directly access the quick status panel and full management console within the DSH sidebar, viewing gateway status, device online status, and token usage in real-time. The plugin features a built-in remote gateway that starts and stops automatically with DSH, listening on 0.0.0.0:8787 by default, and includes Bearer Token authentication as well as gateway self-healing capabilities. Its core functions include file transfer (supporting chunked upload, resume capability, and SHA-256 verification), multi-platform adaptation (providing mobile, desktop WebUI, and Android APK), session management (supporting model switching, sub-agent interruption, image attachments, etc.), and a notification system. During installation, 'w' must be specified.
