feat: add MCP client plugin (dsh-mcp-client)
Connects to an external MCP server and registers its tools on ctx.tools. Supports stdio (child process) and Streamable HTTP transports. Credential-shaped env vars are scrubbed before forwarding to child processes. - Plugin lifecycle: connect, sync tools, re-sync on ToolListChanged, dispose unregisters and closes - Full JSDoc on all exports (@param/@returns on functions) - 100% per-file coverage (apply lifecycle, args coercion, env scrubbing) - Config catalog regenerated
