Add comprehensive GitHub Copilot instructions for React frontend development

[Copilot]

This PR adds a comprehensive .github/copilot-instructions.md file that provides GitHub Copilot with detailed, validated instructions for working effectively with the Glowing Telegram Frontend codebase.

What's Included

The instructions file contains thoroughly tested and validated information covering:

Essential Setup & Commands

• Complete dependency installation process (npm install - 60-90 seconds)
• Environment configuration setup (cp .env.defaults .env)
• All build and test commands with measured execution times
• Critical timeout requirements and "NEVER CANCEL" warnings for long operations

Development Workflow

• Development server setup (npm run start on localhost:5173)
• Storybook component documentation (npm run storybook on localhost:6006)
• Code quality tools (Biome for linting/formatting, TypeScript checking)
• Production build process with expected timing (15-20 seconds)

Manual Validation Requirements

• Specific user scenarios that must be tested after changes
• Navigation flows between Series, Streams, Episodes, and other React Admin pages
• Stream Manager interface testing
• Filter persistence validation procedures

Expected Issues & Workarounds

• Authentication errors in development (normal with placeholder Cognito credentials)
• Build warnings about chunk sizes and any types (expected and documented)
• MSW mock integration for API development

Repository Structure

• Detailed breakdown of /src organization (components, resources, utilities)
• Key configuration files and their purposes
• CI/CD pipeline information for GitHub Actions

Validation Process

Every command and instruction was exhaustively tested:

• ✅ All commands executed successfully with measured timings
• ✅ Development server tested with full application navigation
• ✅ Storybook functionality verified with component interactions
• ✅ Build and test processes validated end-to-end
• ✅ Manual user scenarios tested with screenshots captured

Additional Improvements

• Added storybook-static to .gitignore to prevent build artifacts in version control
• Cleaned up accidentally committed Storybook build files

The instructions follow an imperative tone as requested and provide GitHub Copilot with everything needed to work effectively in this React 19 + TypeScript + Vite frontend codebase without requiring additional context gathering.

Fixes #95.

Warning

Firewall rules blocked me from connecting to one or more addresses

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

• storybook.js.org
  • Triggering command: node /home/REDACTED/work/glowing-telegram-frontend/glowing-telegram-frontend/node_modules/.bin/storybook dev -p 6006 (dns block)
  • Triggering command: node /home/REDACTED/work/glowing-telegram-frontend/glowing-telegram-frontend/node_modules/.bin/storybook build (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)
