✨ Add comprehensive GitHub Copilot coding agent setup

[Copilot]

This PR implements comprehensive GitHub Copilot coding agent instructions and supporting documentation as requested in issue #copilot-setup-steps, following the best practices outlined in the GitHub Copilot coding agent guidelines.

What's Added

🤖 Copilot Instructions (.github/copilot-instructions.md)

A comprehensive 327-line guide that provides GitHub Copilot with deep context about the Onchain Test Kit project, including:

• Project Architecture: Detailed breakdown of core components (Configuration Builder, Wallet Fixtures, Local Node Manager, Smart Contract Manager)
• Technology Stack: Complete overview of TypeScript, Playwright, Viem, and Biome usage patterns
• API Design Principles: Fluent interface patterns and type safety guidelines
• Testing Patterns: Specific examples for wallet interactions, fork mode testing, and DApp integration
• Common Code Patterns: Real-world examples of configuration, wallet actions, and error handling
• File-Specific Guidance: Targeted advice for working with key components like configBuilder.ts and wallet implementations

📚 Contributing Guidelines (CONTRIBUTING.md)

A detailed 318-line contributor guide covering:

• Development setup and workflow
• Code style standards and TypeScript guidelines
• Testing requirements and patterns
• Architecture guidelines for extending wallet support
• Pull request and review process

🎯 GitHub Templates

• Pull Request Template: Comprehensive checklist covering testing, documentation, wallet compatibility, and breaking changes
• Issue Templates: Structured templates for bug reports, feature requests, and documentation issues
• Issue Configuration: Improved issue triage with helpful links and disabled blank issues

Benefits for Copilot

This setup enables GitHub Copilot to:

1. Generate Better Code: With deep understanding of the fluent API patterns and builder design
2. Follow Project Conventions: Consistent error handling, async patterns, and TypeScript usage
3. Create Proper Tests: Using established patterns for wallet automation and fork mode testing
4. Maintain API Consistency: Following the established configuration and action handling patterns

Example: Before vs After

Before: Copilot might suggest generic Playwright code

await page.click('button');

After: Copilot can suggest project-specific wallet interaction patterns

await metamask.handleAction('connect', { shouldApprove: true });
await metamask.handleAction('transaction', { 
  shouldApprove: true,
  gasLimit: '21000' 
});

Quality Assurance

• ✅ All existing tests pass (npm run test)
• ✅ Build process unaffected (npm run build)
• ✅ Linting passes (npm run lint)
• ✅ Zero breaking changes to existing functionality
• ✅ Documentation-only changes with comprehensive examples

This implementation provides GitHub Copilot with the context needed to understand the project's blockchain testing domain, wallet automation patterns, and architectural decisions, enabling more accurate and helpful code suggestions for contributors.

.github/copilot-instructions.md[nitpick] The project description mentions 'end-to-end testing toolkit' but doesn't clarify what 'Onchain' specifically means in this context. Consider adding a brief explanation of what 'onchain' refers to (blockchain-based testing, on-chain interactions, etc.) to help Copilot better understand the domain.

Suggested change

The Onchain Test Kit is an end-to-end testing toolkit for blockchain applications, powered by Playwright. It provides comprehensive wallet automation and testing capabilities for DApps with support for MetaMask, Coinbase Wallet, and Phantom wallets.

The Onchain Test Kit is an end-to-end testing toolkit for blockchain applications, powered by Playwright. Here, "onchain" refers to interactions and testing that occur directly on blockchain networks—such as deploying and interacting with smart contracts, simulating transactions, and verifying on-chain state changes. It provides comprehensive wallet automation and testing capabilities for DApps with support for MetaMask, Coinbase Wallet, and Phantom wallets. @copilot-instructions.mdhttps://api.githubcopilot.com/mcp/readonly

The import statement uses '@coinbase/onchaintestkit' but the repository URL suggests this might not be the correct package name. Verify that this matches the actual published package name or update it to reflect the correct import path.

Suggested change

	import { createOnchainTest } from '@coinbase/onchaintestkit';
	import { createOnchainTest } from '@coinbase/onchain-testkit';
