Add a `client-setup` command to the published `@penpot/mcp` package. When invoked as `penpot-mcp client-setup`, the bin delegates to the `add-mcp` CLI against the local MCP server URL (from `PENPOT_MCP_SERVER_PORT`, default 4401), run via npx. Update docs on MCP client configuration. Recommend calling `add-mcp` directly for now, since the `client-setup` command only becomes available once a new `@penpot/mcp` release is published to npm.
