dsh-mcp-skill-manager: MCP and Skill Library Management Panel for DeepSeek Harness

Configuration for DeepSeek Harness (DSH) MCP servers and the skill library is fragmented. This plugin provides a visual dashboard for centralized management. Core features include managing server status, testing connections, and estimating tool tokens in the MCP panel; browsing and creating skills, with support for batch operations and grouping by collection or rule in the Skills panel; and using a rule editor to automatically categorize skills. The plugin requires write permissions and aims to reduce configuration complexity for DSH users.
