Add Redis Package Challenge Series

Issue Description

Create a comprehensive Redis package challenge series to teach developers how to use Redis with Go for caching, session management, and real-time applications.

What needs to be implemented

Package Structure

Create packages/redis/ with the following challenges:

1. Challenge 1: Basic Operations & Caching (Beginner)

   • Redis connection and basic commands (GET, SET, DEL)
   • String operations and expiration
   • Build a simple cache layer for a web application

2. Challenge 2: Data Structures & Sessions (Intermediate)

   • Lists, Sets, Hashes, and Sorted Sets
   • Session management implementation
   • Shopping cart functionality using Redis data structures

3. Challenge 3: Pub/Sub & Real-time Features (Intermediate)

   • Redis Pub/Sub messaging
   • Real-time chat application
   • Event-driven architecture patterns

4. Challenge 4: Advanced Features & Performance (Advanced)

   • Redis Streams for event sourcing
   • Lua scripting for atomic operations
   • Connection pooling and performance optimization

Required Files for Each Challenge

• README.md - Challenge description and requirements
• solution-template.go - Starting code template with TODOs
• solution-template_test.go - Comprehensive test suite
• learning.md - Educational content (400+ lines)
• hints.md - Step-by-step guidance
• metadata.json - Challenge metadata
• go.mod and go.sum - Dependencies
• run_tests.sh - Testing script

Learning Objectives

• Master Redis fundamentals and Go client usage
• Implement caching strategies for web applications
• Build real-time features with Pub/Sub
• Understand Redis data structures and their use cases
• Learn performance optimization techniques
• Practice with production-ready patterns

Resources

• Redis Go Client Documentation
• Redis Official Documentation
• Existing package challenges for reference

Acceptance Criteria

• All 4 challenges implemented with complete file structure
• Each challenge has comprehensive tests (90%+ coverage)
• Learning materials are detailed and educational
• Code follows existing repository patterns and style
• All tests pass and scripts work correctly
• Documentation is clear and beginner-friendly

Getting Started

1. Study existing package challenges in packages/gin/ or packages/mongodb/
2. Set up Redis locally or use Redis Cloud
3. Follow the package challenge structure from CONTRIBUTING.md
4. Start with Challenge 1 and build progressively
