dsh-float-chat: DSH Sidebar Pinned Floating Chat Window

`dsh-float-chat` is a standalone floating window plugin developed specifically for DSH to resolve the issue of the sidebar being obscured. Built with WinForms + WebView2, the floating window can stay on top and overlay other applications, and supports four display modes, window position memory, multi-conversation management, and burn-after-use security features. The plugin also includes cache clearing and token statistics. It requires the WebView2 Runtime in a Windows environment and depends on the specified client plugin to use.
