@visol-456/dsh-web-compat: Fix Web Compatibility for HTTP Access over LAN

The DeepSeek Harness plugin `@visol-456/dsh-web-compat` is designed to resolve compatibility issues in non-secure contexts, such as HTTP on a local area network. The plugin provides a status panel on the settings page and injects a `crypto.randomUUID` polyfill in insecure contexts, fixing crashes during image attachment uploads caused by the missing native API. After installation, DSH Web runs stably in HTTP-only local area network environments.
