Add GitHub Actions workflows for GitHub Pages and Firebase Hosting deployment

[Copilot]

Adds automated deployment pipelines to GitHub Pages and Firebase Hosting.

Changes

Workflows (.github/workflows/)

• deploy-github-pages.yml - Builds and deploys to GitHub Pages on push to master
• deploy-firebase.yml - Builds and deploys to Firebase Hosting on push to master

Both workflows:

• Install npm + bower dependencies
• Compile SCSS → CSS and JSX → JS via gulp
• Support manual triggering via workflow_dispatch
• Use explicit permissions (CodeQL validated)

Configuration

• firebase.json - Hosting config, excludes source files (.scss, .jsx, etc.)
• .gitignore - Excludes .firebase/ and .firebaserc

Required Secrets

GitHub Pages: None (uses built-in GITHUB_TOKEN)

Firebase Hosting:

• FIREBASE_SERVICE_ACCOUNT - JSON service account key from Firebase Console → Project Settings → Service Accounts
• FIREBASE_PROJECT_ID - Project ID from Firebase Console → Project Settings → General

Enable GitHub Pages via Settings → Pages → Source: "GitHub Actions"

Original prompt
