[Copilot]

This PR adds detailed deployment documentation to the project README, explaining how the automated deployment process works for the Glowing Telegram Frontend, including both comprehensive setup instructions and advanced version management capabilities.

Changes Made

Added a new "Deployment" section to README.md that covers:

How to Deploy

• Step-by-step instructions for triggering manual deployments via GitHub Actions
• Clear explanation of required inputs (release version, environment selection, and rollback version)

Prerequisites

• Repository environment configuration requirements in GitHub
• Complete list of all required environment variables with descriptions:
  • AWS configuration (AWS_REGION, AWS_ROLE_ARN, BUCKET_NAME)
  • Authentication setup (COGNITO_CLIENT_ID, COGNITO_USER_POOL_ID, COGNITO_DOMAIN)
  • API endpoints (API_URL, WEBSOCKET_URL, CONTENT_URL)
  • External integrations (TWITCH_CLIENT_ID)
  • Redirect URIs (LOGOUT_URI, REDIRECT_URI)

Deployment Process

• Detailed workflow explanation covering all steps from code checkout to S3 deployment
• Node.js setup, dependency installation, building with environment variables, AWS authentication, file sync, and version info creation

Frontend Version Management

• Advanced version management system with comprehensive config/version.json file
• Explanation of versioned deployments to separate S3 paths
• Instant rollback capabilities without redeployment
• Version metadata including deployment environment and timestamps

Release Versioning

• Semantic versioning guidelines and examples
• S3 path structure (s3://bucket-name/release-version/)
• Benefits of versioned deployments for rollbacks and multiple environment hosting

Local Build Testing

• Instructions for testing production builds locally before deployment using npm run build and npm run serve

Workflow Enhancements

The PR also includes merged workflow improvements from main:

• Added rollbackVersion input parameter to publish.yml
• Added version info creation and upload steps that generate comprehensive deployment metadata
• Enhanced deployment process with automated version tracking

The documentation is strategically positioned between the Project Structure and Contributing sections, maintaining the README's logical flow while providing essential deployment information for maintainers and contributors.

Fixes #97.
