Rewrite GitHub Pages deployment with official Next.js workflow and modern best practices

[Copilot]

This PR completely rewrites the GitHub Pages deployment configuration to use GitHub's official Next.js workflow template and follows current best practices for static site deployment.

Problem Statement

The existing deployment workflow had several issues:

• Used custom deployment logic instead of GitHub's official templates
• Complex conditional configuration in next.config.ts with redundant settings
• Build artifacts were being committed to version control
• Outdated workflow patterns and suboptimal caching
• Missing comprehensive CI validation across Node.js versions

Solution

🔄 Workflow Modernization

• Removed custom deploy.yml and copilot-validation.yml workflows
• Added .github/workflows/nextjs.yml using GitHub's official Next.js Pages template
• Added .github/workflows/ci.yml for comprehensive continuous integration testing

⚙️ Configuration Simplification

• Simplified next.config.ts to essential static export settings only
• Removed complex conditional logic and redundant GitHub Pages configurations
• Updated package.json to remove custom build:github-pages script
• Fixed .gitignore to properly exclude build artifacts (/out/ directory)

📚 Documentation Update

• Rewrote docs/github-pages-deployment.md with current best practices
• Added clear setup instructions for repository settings
• Included troubleshooting guide and maintenance recommendations

Key Benefits

🚀 Performance & Reliability

• Automatic package manager detection (npm/yarn) with optimized caching
• Smart build caching reduces deployment time significantly
• Built-in Next.js configuration inference by GitHub Actions
• Proper concurrency control prevents deployment conflicts

🔒 Security & Standards

• Uses official GitHub Actions with proper permission scoping
• GITHUB_TOKEN permissions follow principle of least privilege
• Multi-Node.js version testing (18, 20, 22) ensures compatibility
• Future-proof setup that adapts to GitHub Pages changes automatically

🛠️ Developer Experience

• Cleaner codebase with simplified configuration files
• Better error reporting and debugging through official workflow logs
• Comprehensive CI catches issues before deployment
• Reduced maintenance overhead with standardized approach

Technical Details

The new workflow:

1. Automatically detects package manager and configures appropriate caching
2. Uses actions/configure-pages@v5 with Next.js-specific optimizations
3. Generates static export to /out directory (properly gitignored)
4. Deploys using actions/deploy-pages@v4 with proper artifact handling

Repository Setup Required

After merging, ensure repository settings are configured:

• Settings → Pages → Source: Set to "GitHub Actions"
• Settings → Actions → General: Allow all actions and workflows
• Workflow permissions: "Read and write permissions"

Validation

• ✅ TypeScript compilation passes without errors
• ✅ Linting passes all checks
• ✅ Build process successfully generates all 22 static pages
• ✅ Static export creates proper /out directory structure
• ✅ Workflow syntax validated as correct GitHub Actions YAML

This modernization brings the deployment configuration in line with current GitHub Pages and Next.js best practices, ensuring reliable, performant, and maintainable deployments.

Original prompt

Review whole repository's codes and docs and the Github Page Deployment configurations and files based on the @github/docs/files/content/pages directories all md files (including the sub folder). Remove all the exisiting worflows and based on the docs from @github/docs/files/content/pages rewrite the Deployment for Next.js project in Github Pages using Build and deployment Source: Github Actions in Repository Pages settings has been setted.

The remote pattern configuration is incorrect. GitHub profile images are served from avatars.githubusercontent.com, not github.com. The pathname should match the actual GitHub avatar URL structure.

Suggested change

	hostname: "github.com",
	pathname: "/CodeStorm-Hub/**",
	hostname: "avatars.githubusercontent.com",
	pathname: "/u/**",

The cache key pattern **.[jt]s and **.[jt]sx will not match TypeScript and JSX files correctly. The pattern should be **/*.{js,jsx,ts,tsx} to properly match file extensions.

Suggested change
