Add comprehensive GitHub Copilot instructions for SnapDeploy development workflow

[Copilot]

Creates a detailed .github/copilot-instructions.md file that provides GitHub Copilot coding agents with comprehensive guidance for working effectively in the SnapDeploy codebase.

Key Features

Validated Commands with Exact Timing

• All commands tested and measured in real environment
• Frontend build: 3.7 seconds, npm install: 29 seconds
• API server npm install: 29 seconds
• Build server npm install: 2 seconds
• S3 reverse proxy npm install: 1.5 seconds

Multi-Component Architecture Guide

• React + Vite frontend with TailwindCSS
• Express.js API server with MongoDB/Mongoose
• Automated build service with Docker deployment
• S3 reverse proxy for static site serving

Manual Validation Scenarios
Since no automated tests exist, the instructions provide detailed manual validation workflows:

• Frontend: build verification, linting, dev server startup, UI navigation testing
• API server: expected startup failures without environment configuration
• Build server: Docker-based deployment pipeline understanding

Critical Timeout and Cancellation Warnings

• Explicit "NEVER CANCEL" warnings for long-running operations
• Build processes can take 5-10 minutes with 15+ minute timeout requirements
• Prevents premature cancellation of deployment builds

Expected Error Documentation

• ESLint shows exactly 45 errors and 9 warnings (normal behavior)
• API server crashes with environment variable errors (expected without proper setup)
• Build server uses multiple npm install strategies for dependency conflicts

Development Workflow Guidance

• Step-by-step instructions for adding frontend features
• API endpoint modification procedures
• Build system change protocols
• Common issue troubleshooting

The instructions emphasize always following the documented procedures first before falling back to additional search or exploration, ensuring consistent and efficient development practices.

Fixes #2.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• binaries.prisma.sh
  • Triggering command: node scripts/postinstall.js (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

@Pavan0228 👋 This repository doesn't have Copilot instructions. With Copilot instructions, I can understand the repository better, work faster and produce higher quality PRs.

I can generate a .github/copilot-instructions.md file for you automatically. Click here to open a pre-filled issue and assign it to me. I'll write the instructions, and then tag you for review.
