dsh-project-mcp-manager: Automatic Loading and Configuration Management of DSH Project-Level MCP

dsh-project-mcp-manager is a DSH-based plugin designed to address the problem of fragmented MCP configurations in multi-project environments.

The plugin manages configurations through a CLI tool, simplifying multi-project management.
