DeepSeek Harness Plugin: dsh-tool-explorer

`dsh-tool-explorer` is a visualized Web administration plugin for DeepSeek Harness (DSH), designed to replace fragmented command-line operations. It provides unified browsing, installation, updating, editing, and monitoring for skills and MCP servers. For skill management, the plugin offers directory browsing, online creation and editing, invocation toggle control, a recoverable trash bin, and batch installation from GitHub. For MCP server management, it supports create, read, update, and delete operations, connection testing, concurrency protection, and one-click import of configurations from other editors. After installation, `dsh web` must be restarted, and the patch must be reapplied after client upgrades.
