Pull Request Overview

This PR adds Cursor IDE configuration rules to define coding patterns and conventions across the Hypergraph monorepo. The rules are organized by package/application type to provide context-specific guidance for development.

• Establishes coding standards and architectural patterns for each package and application
• Implements project-wide rules for consistent development practices across the monorepo
• Provides technology-specific guidance for different parts of the codebase (React, Next.js, CLI tools, etc.)
