Move stdio transports to a ./stdio subpath export. Import StdioClientTransport, getDefaultEnvironment, DEFAULT_INHERITED_ENV_VARS, and StdioServerParameters from @modelcontextprotocol/client/stdio, and StdioServerTransport from @modelcontextprotocol/server/stdio. The package root entries no longer pull in node:child_process, node:stream, or cross-spawn, fixing bundling for browser and Cloudflare Workers targets. Node.js, Bun, and Deno consumers update the import path; runtime behavior is unchanged.
