feat: Complete PII cleanup and fully automatic pipeline

🧹 PII Cleanup & Security: - Remove all hardcoded domains (darknex.us, hndrx.co) - Remove all hardcoded emails (admin@ references) - Replace all personal info with environment variables - Repository now 100% generic and reusable 🚀 Fully Automatic Pipeline: - Pipeline now runs automatically develop → staging → production - No manual intervention required for production promotions - Auto-promotion triggers after successful tests - All workflows use commit-specific image tags 🔧 Environment Variables: - All manifests use ${VARIABLE_NAME} syntax - All scripts source from .env file - GitHub Actions use secrets for sensitive data - Complete .env.example template provided 📚 Documentation: - New comprehensive WORKFLOWS.md with pipeline details - New PIPELINE_QUICK_REFERENCE.md for quick reference - Updated all docs to use generic placeholders - Added security/privacy section to README 🔐 Security Enhancements: - Updated .gitignore for all sensitive files - Created PII verification script (verify-pii-removal.sh) - Created cleanup automation script (cleanup-pii.sh) - Repository verified PII-free and production-ready BREAKING: Repository now requires .env configuration - Copy .env.example to .env and configure for your environment - Set GitHub repository secrets for CI/CD workflows - All deployments now use environment-specific configuration

+- **Comprehensive Testing**: Smoke tests after each deployment
+- **Manual Controls**: Override any step with manual workflows
+- **Zero-downtime Deployments**: Blue-green strategy for production
+- **Security**: Webhook signature validation and environment-specific secrets

+# 🚀 Fully Automatic CI/CD Pipeline
+
+## Pipeline Flow
+```
+Push to develop → Build → Deploy Dev → Test Dev → 
+Promote to Staging → Build → Deploy Staging → Test Staging →
+Promote to Production → Build → Deploy Production → Test Production
+```
+
+## Key Features
+✅ **Zero Manual Intervention** - Fully automatic from develop to production  
+✅ **Smart Testing** - Tests run after deployments, not before  
+✅ **Safe Rollouts** - Each environment tested before promotion  
+✅ **Commit Tracking** - Each deployment uses exact commit-tagged images  
+✅ **Emergency Override** - Manual actions available if needed  
+
+## Environments
+
+| Environment | URL | Deployment Trigger |
+|-------------|-----|-------------------|
+| 🧪 Development | Your configured development domain | Push to `develop` |
+| 🎭 Staging | Your configured staging domain | After dev tests pass |
+| 🚀 Production | Your configured production domain | After staging tests pass |
+
+## How It Works
+
+1. **Developer pushes to `develop`**
+   - Automatically builds image: `develop-abc1234`
+   - Deploys to development environment
+   - Runs smoke tests on the new deployment
+
+2. **Dev tests pass**
+   - Automatically merges `develop` → `staging`
+   - Builds staging image: `staging-def5678`
+   - Deploys to staging environment
+   - Runs smoke tests on staging
+
+3. **Staging tests pass**
+   - Automatically merges `staging` → `main`
+   - Builds production image: `main-ghi9012`
+   - Deploys to production environment
+   - Runs smoke tests on production
+
+## Emergency Actions
+
+If the automatic pipeline breaks, these manual actions are available:
+
+- **Emergency Production Deploy**: Actions → "Deploy to Production" (type "DEPLOY")
+- **Force Promotion**: Actions → "Auto-Promote to Production"
+- **Check Status**: Actions → "Deployment Status Check"
+- **Test Environments**: Actions → "Smoke Tests"
+
+## Monitoring
+
+- **Pipeline Status**: Check GitHub Actions tab
+- **Environment Health**: Run "Deployment Status Check" workflow
+- **Live Monitoring**: Each environment URL shows current version
+
+---
+
+**🎯 Result**: Push code to `develop`, and it automatically flows through all environments to production with full testing at each stage!

+
+### Key Principles
+
+- **Fully Automatic**: Zero manual intervention from develop to production
+- **No Race Conditions**: Each step waits for the previous to complete
+- **Test After Deploy**: Smoke tests run on newly deployed versions
+- **Commit-Specific Images**: Each environment uses exact commit-tagged images
+- **Automatic Promotion**: Successful tests trigger automatic promotion
+- **Manual Override**: Emergency manual deployment still available
+
+## 🔧 Workflow Details
+
+### 1. Build and Push Container Image (`build-image.yml`)
+
+**Triggers:**
+- Push to `main`, `develop`, `staging`
+- Pull requests to these branches
+
+**What it does:**
+- Builds Docker image from current commit
+- Creates commit-specific tags: `{branch}-{commit-hash}`
+- Pushes to GitHub Container Registry (GHCR)
+- Provides foundation for all deployments
+
+**Tags created:**
+- `develop-abc1234` (for develop branch)
+- `staging-def5678` (for staging branch) 
+- `main-ghi9012` (for main branch)
+
+### 2. Deploy to Development (`deploy-dev.yml`)
+
+**Triggers:**
+- After "Build and Push Container Image" completes successfully on `develop`
+- Manual dispatch
+
+**What it does:**
+- Waits for build to complete (no race conditions)
+- Uses exact commit-tagged image that was just built
+- Deploys via webhook to k3s development namespace
+- Sets up development environment
+
+**Dependencies:**
+- Requires successful build completion
+- Uses environment secrets: `DEV_WEBHOOK_URL`, `WEBHOOK_SECRET`
+
+### 3. Smoke Tests (`smoke-test.yml`)
+
+**Triggers:**
+- After any deployment completes ("Deploy to Development", "Deploy to Staging", "Deploy to Production")
+- Scheduled every 6 hours
+- Manual dispatch
+
+**What it does:**
+- Tests the **newly deployed** version (not previous)
+- Validates canonical Knative domains
+- Checks content, performance, SSL certificates
+- Runs environment-specific tests
+
+**Environments tested:**
+- 🧪 Development: Your configured development domain
+- 🎭 Staging: Your configured staging domain  
+- 🚀 Production: Your configured production domain
+
+### 4. Auto-Promote Pipeline (`auto-promote.yml`)
+
+**Triggers:**
+- After "Smoke Tests" complete successfully on `develop` branch
+
+**What it does:**
+- Verifies development smoke tests passed
+- Merges `develop` → `staging` automatically
+- Triggers staging deployment pipeline
+- Creates promotion summary
+
+**Safety features:**
+- Only runs if smoke tests pass
+- Handles "already up to date" scenarios gracefully
+
+### 5. Deploy to Staging (`deploy-staging.yml`)
+
+**Triggers:**
+- Push to `staging` branch (triggered by auto-promotion)
+- After "Auto-Promote Pipeline" completes
+- Manual dispatch
+
+**What it does:**
+- Builds and deploys staging-specific image
+- Uses `staging-{commit}` tagged image
+- Deploys via webhook to k3s staging namespace
+
+### 6. Auto-Promote to Production (`promote-to-production.yml`)
+
+**Triggers:**
+- After "Smoke Tests" complete successfully on `staging` branch (AUTOMATIC)
+- Manual dispatch (emergency override only)
+
+**What it does:**
+- Verifies staging smoke tests passed
+- Merges `staging` → `main` automatically
+- Triggers production deployment immediately
+- Creates production promotion summary
+
+**Automation features:**
+- Runs automatically after staging tests pass
+- No manual confirmation required
+- Seamless promotion from staging to production
+
+### 7. Deploy to Production (`deploy-prod.yml`)
+
+**Triggers:**
+- Push to `main` branch (triggered by auto-promotion) - AUTOMATIC
+- Manual dispatch (requires typing "DEPLOY" for emergencies)
+
+**What it does:**
+- Automatically deploys when main branch is updated
+- Uses `main-{commit}` tagged image
+- Deploys via webhook to k3s production namespace
+- Blue-green deployment strategy for zero downtime
+
+**Automation features:**
+- No manual confirmation required for automatic deployments
+- Immediate deployment after staging promotion
+- Manual override still available for emergencies
+
+### 8. Deployment Status Check (`deployment-status.yml`)
+
+**Triggers:**
+- Manual dispatch
+- Scheduled every 4 hours
+
+**What it does:**
+- Checks health of all environments
+- Shows current versions deployed
+- Provides manual action options
+- Creates comprehensive status report
+

+
+## 🔍 Troubleshooting
+
+### Common Issues
+
+#### Pipeline Not Triggering
+
+**Symptoms:** New commit pushed but no workflows start
+**Causes:**
+- Workflow file syntax error
+- Missing required secrets
+- Branch protection rules blocking
+
+**Solutions:**
+1. Check workflow syntax in `.github/workflows/`
+2. Verify all secrets are set in repository settings
+3. Check Actions tab for error messages
+
+#### Deployment Fails
+
+**Symptoms:** Deployment workflow fails
+**Causes:**
+- Webhook endpoint unreachable
+- Invalid webhook signature
+- k3s cluster issues
+- Image not found
+
+**Solutions:**
+1. Check webhook handler logs: `kubectl logs -n webhook-system deployment/webhook-handler`
+2. Verify webhook secret matches between GitHub and cluster
+3. Confirm image exists in GHCR
+4. Check k3s cluster health
+
+#### Smoke Tests Fail
+
+**Symptoms:** Tests report environment unreachable
+**Causes:**
+- DNS resolution issues
+- SSL certificate problems
+- Application not responding
+- Ingress configuration issues
+
+**Solutions:**
+1. Test domains manually: `curl -I https://${DEV_CANONICAL_DOMAIN}`
+2. Check Knative service status: `kubectl get ksvc -A`
+3. Verify ingress configuration: `kubectl get ingress -A`
+4. Check certificate status: `kubectl get certificates -A`
+
+#### Auto-Promotion Not Working
+
+**Symptoms:** Tests pass but promotion doesn't happen
+**Causes:**
+- Workflow permission issues
+- No new commits to merge
+- Dependency chain broken
+
+**Solutions:**
+1. Check workflow permissions in repository settings
+2. Verify branch protection rules
+3. Check workflow run logs in Actions tab
+4. Manual promotion as fallback
+
+### Debug Commands
+
+```bash
+# Check all environments
+kubectl get all -A | grep game-2048
+
+# Check webhook handler
+kubectl logs -n webhook-system deployment/webhook-handler --tail=50
+
+# Check Knative services
+kubectl get ksvc -A
+
+# Check ingress
+kubectl get ingress -A
+
+# Test webhook endpoint
+curl -X POST -H "Content-Type: application/json" \
+  -d '{"test": "true"}' \
+  https://your-webhook-url/webhook
+
+# Check DNS resolution
+dig ${DEV_CANONICAL_DOMAIN}
+
+# Test SSL certificate
+openssl s_client -servername ${DEV_CANONICAL_DOMAIN} \
+  -connect ${DEV_CANONICAL_DOMAIN}:443
+```
+
+### Emergency Procedures
+
+#### Rollback Production
+1. Identify last known good commit/tag
+2. Run "Deploy to Production" manually
+3. Specify the good image tag
+4. Type "DEPLOY" to confirm
+
+#### Skip Failed Tests
+1. Run "Promote to Production" manually
+2. Type "PROMOTE" to confirm
+3. Enable "Skip tests" if staging already validated
+
+#### Force Promotion
+1. Manually merge branches using git
+2. Push to trigger deployments
+3. Monitor via "Deployment Status Check"
