feat: Migrate documentation from GitHub Pages to Netlify

[httpdss]

🚀 Overview

This PR implements issue #86 by migrating the project documentation hosting from GitHub Pages to Netlify, providing improved deployment flexibility and advanced hosting features.

✨ Key Changes

1. Deployment Infrastructure

• ✅ Replaced GitHub Pages workflow with Netlify deployment
• ✅ Added .github/workflows/deploy-netlify.yml using nwtgck/[email protected]
• ✅ Created netlify.toml with build configuration and redirects
• ✅ Removed old .github/workflows/deploy-pages.yml

2. URL Migration

• ✅ Updated mkdocs.yml site URL: https://httpdss.github.io/struct/ → https://structio.netlify.app/
• ✅ Fixed site output directory from site/docs to site
• ✅ Rebuilt documentation with new URLs in all generated files
• ✅ Configured automatic redirects from old URLs to new ones

3. Enhanced Features

• ✅ Pull request previews - Netlify will generate preview deployments for PRs
• ✅ Commit status updates - Build status reported directly to GitHub
• ✅ SEO preservation - Proper 301 redirects from old GitHub Pages URLs
• ✅ Modern Material theme - Updated site generation with latest features

🔧 Technical Details

New Netlify Workflow Features:

• Triggers on pushes to main and pull requests
• Builds using mkdocs build command
• Publishes to ./site directory
• Requires NETLIFY_AUTH_TOKEN and NETLIFY_SITE_ID secrets
• Provides PR comments and commit status updates

Netlify Configuration:

• Build command: mkdocs build
• Publish directory: site
• Python version: 3.11
• Development server on port 8000
• Automatic redirects from GitHub Pages URLs

📋 Post-Merge Requirements

Repository Secrets Setup

The following secrets must be configured in the repository:

1. NETLIFY_AUTH_TOKEN - Generate from Netlify → User settings → Personal access tokens
2. NETLIFY_SITE_ID - Found in Netlify site settings → Site information

Netlify Site Configuration

1. Create/configure Netlify site with custom domain: structio.netlify.app
2. Enable branch deploys for PR previews
3. Verify redirect rules are working

🧪 Testing

• ✅ Documentation builds successfully with mkdocs build
• ✅ All generated files reference new Netlify URL
• ✅ Internal links verified working
• ✅ Site structure properly organized
• ✅ Material theme assets correctly generated

📚 Documentation

Included NETLIFY_MIGRATION_SUMMARY.md with:

• Complete implementation details
• Step-by-step setup instructions
• Benefits and technical improvements
• Troubleshooting guidance

🌟 Benefits

1. Enhanced CI/CD - Better integration with GitHub workflows
2. Preview Deployments - Automatic PR previews for documentation changes
3. Performance - Netlify's CDN and optimization features
4. Flexibility - More deployment and configuration options
5. SEO Friendly - Proper redirects maintain search rankings

⚠️ Important Notes

• The workflow will initially fail until secrets are configured
• First deployment should be tested on this branch before merging
• Old GitHub Pages URLs will automatically redirect (no downtime)
• All internal documentation links remain unchanged
