This PR transforms the TypeScript cheat sheet from a basic language reference into a strategic, security-first guide for mid-level developers, following the improved pattern established by the Python cheat sheet.

Key Improvements

Strategic Focus

  • Security-first approach: Emphasizes type safety as a security feature, input validation, and safe coding patterns
  • Performance-oriented: Includes compilation optimization, memory management, and React performance patterns
  • Real-world patterns: Focuses on practical patterns developers use daily rather than just syntax

New Structure

The cheat sheet has been completely restructured into 5 strategic sections:

  1. TypeScript Essentials & Security - Type guards, input validation, null safety patterns
  2. Performance & Type System Optimization - Efficient types, compiler optimizations, build performance
  3. React Performance Patterns - Optimized hooks, memoization, component splitting
  4. Error Handling & Robustness - Result types, validation chains, defensive programming
  5. Testing & Development Workflow - Type-safe testing, production configuration, performance monitoring

Security Enhancements

  • Type guards for runtime validation
  • Input sanitization patterns
  • Safe API error handling
  • Branded types for additional type safety
  • Comprehensive validation examples

Performance Focus

  • Compilation optimization tips
  • Memory-efficient patterns
  • React performance best practices
  • Build configuration optimization
  • Performance monitoring utilities

Developer Experience

  • Strategic annotations (🔒 Security, ⚡ Performance, 💡 Best Practices)
  • Real-world examples with context
  • Production-ready code patterns
  • Type-safe testing strategies

Before vs After

Before: Basic TypeScript syntax reference with simple examples
After: Strategic guide with security patterns, performance optimization, and production-ready examples

The improved cheat sheet now provides actionable patterns that developers can immediately apply in their projects, making it a valuable reference for building secure, performant TypeScript applications.

- Common mistakes highlighted with ✅ Good vs ❌ Bad examples
- Progressive complexity: beginner → intermediate → advanced → expert
- Proper difficulty levels and tags on every example
- Documentation links to official sources

Search Foundation:
- Installed Fuse.js (v7) for upcoming fuzzy search implementation
- Prepared infrastructure for typo-tolerant search
- Foundation for relevance scoring and smart suggestions

Navigation & UX:
- Updated navigation with 4 new cheat sheets (10 total now)
- Added proper Lucide React icons:
  * GitBranch for Git
  * Container for Docker
  * Atom for React
  * Regex for Regex patterns
- Reorganized menu for better discoverability
- Homepage updated to showcase all 10 cheat sheets

Technical:
