Complete GitHub Copilot setup with comprehensive cross-references and embedded content

[Copilot]

This PR completes the GitHub Copilot setup by enhancing instruction files with comprehensive cross-references and significantly expanding the main Copilot instructions file to include embedded content from specialized instruction files for better AI agent accessibility.

Changes Made

📚 Main Copilot Instructions Enhancement

• Expanded .github/copilot-instructions.md from ~328 lines to 1,345+ lines (317% increase)
• Embedded comprehensive content directly from specialized instruction files:
  • Wallet Integration Instructions (lines 331-698)
  • Testing Instructions (lines 699-1093)
  • Development Instructions (lines 1094-1345)
• Maintained original structure while adding detailed guidance for blockchain testing scenarios

🔗 Cross-Reference System Implementation

Added consistent cross-references to all specialized instruction files:

• .github/instructions/development.instructions.md
• .github/instructions/testing.instructions.md
• .github/instructions/wallet-integration.instructions.md

Each file now references related instruction files (AGENTS.md, copilot-instructions.md, and peer files) providing comprehensive navigation context for AI agents.

🎯 Content Quality Assurance

• Synchronized embedded content with source files (verified via diff comparison)
• Maintained consistent formatting and structure across all instruction files
• Preserved specialized file independence while enhancing discoverability
• Enhanced AI agent accessibility through centralized comprehensive guidance

Impact

This enhancement significantly improves the GitHub Copilot experience by:

• Centralizing comprehensive guidance in a single main file for quick reference
• Maintaining specialized instruction files for focused development areas
• Providing 4x more detailed context for AI agents working on blockchain testing
• Enabling seamless navigation between different instruction areas through cross-references

The GitHub Copilot setup now provides comprehensive, well-organized guidance covering wallet integration, testing methodologies, and development practices specifically tailored for the Onchain Test Kit project.
