chore: update dependencies and improve CLI functionality
- Update `@mcp-ui/server` patch hash in `pnpm-lock.yaml`. - Add new dependencies for `@langchain` packages in `pnpm-lock.yaml`. - Restore `express` version in `pnpm-lock.yaml`. - Enhance CLI to dynamically read package version from `package.json`. - Implement workspace dependency handling in `create-mcp-use-app`. - Add a new standalone example for the MCP server. - Refactor favicon proxy and middleware for improved functionality. - Introduce shared utilities for favicon fetching and caching. - Update inspector package to support new features and improve error handling.
