Improve documentation for game modders: beginner-friendly README and comprehensive AI agent guide

[Copilot]

This PR completely rewrites the project documentation to better serve the target audience of game modders, who are often young developers and non-native English speakers. The changes address the core issue of making GABS accessible and attractive to the modding community.

Key Changes

🎮 README.md - Now Modder-Focused

The README has been transformed from a sparse technical document to an engaging, beginner-friendly guide that:

• Starts with motivation: Clear explanation of WHY this helps mod development (AI-powered debugging, testing, development assistance)
• Uses simple language: Easy to understand for non-native speakers with emojis and clear structure
• Emphasizes universality: Makes it crystal clear this works with ANY game, ANY AI, and ANY operating system
• Provides real examples: Concrete use cases like "Ask AI to test your new crafting recipe while you code"
• Includes quick start guide: Step-by-step instructions for immediate success
• Covers all launch modes: DirectPath, Steam, Epic, and CustomCommand examples
• Addresses common questions: FAQ section for typical modder concerns

🤖 AGENTS.md - Comprehensive AI Integration Guide

Created a detailed implementation guide for AI agents and developers that includes:

• Architecture overview: Clear MCP ↔ GABS ↔ GABP ↔ Game flow diagram
• MCP integration patterns: Tools, resources, and events with TypeScript examples
• Advanced AI patterns: Game state monitoring, automated testing, AI-assisted debugging
• GABP protocol details: Message formats and error handling for debugging
• Game mod integration: Complete C# examples for implementing GABP in mods
• Best practices: Performance optimization, caching, testing, and security
• Platform configuration: OS-specific paths and environment variables

Impact

These changes make GABS much more accessible to the game modding community by:

1. Clearly communicating the value proposition for mod development
2. Providing step-by-step guidance for getting started
3. Emphasizing the universal nature (works with any game/AI/OS)
4. Including comprehensive examples and best practices
5. Using beginner-friendly language and formatting

The documentation now properly positions GABS as a universal bridge that democratizes AI-game integration for the modding community.
