feat(ci): add format check, PR validation, and Docker buildx

- Add cargo fmt --check to enforce code formatting - Add pull_request trigger for PR validation - Split workflow into parallel jobs (format, clippy, build, docker) - Integrate Docker Buildx with DinD service - Add BuildKit caching for faster builds - Add local test script (scripts/test-ci-locally.sh) - Add comprehensive documentation All local CI checks pass ✅

+# CI/CD Improvements - Format Check, PR Validation, and Docker Buildx
+
+**Date**: 2026-03-17  
+**Status**: ✅ Implemented  
+**Author**: AI Agent
+
+---
+
+## Summary
+
+Enhanced the Forgejo CI/CD pipeline with three major improvements:
+1. **Format checking** - Enforces consistent code style
+2. **PR validation** - Automated checks for pull requests
+3. **Docker Buildx** - Multi-platform Docker builds with caching
+
+---
+
+## Changes Made
+
+### 1. Pull Request Validation
+
+**Before**:
+```yaml
+on:
+  push:
+    branches: [main]
+```
+
+**After**:
+```yaml
+on:
+  push:
+    branches: [main, develop]
+  pull_request:
+    branches: [main, develop]
+```
+
+**Benefits**:
+- ✅ Validates code before merging to main
+- ✅ Catches issues early in development cycle
+- ✅ Supports `develop` branch workflow
+- ✅ Provides automated feedback on PRs
+
+---
+
+### 2. Code Format Checking
+
+**New Job**: `format`
+```yaml
+format:
+  name: Check Code Formatting
+  runs-on: docker
+  container:
+    image: rust:1.83-slim
+  
+  steps:
+    - name: Checkout code
+      uses: actions/checkout@v4
+    
+    - name: Check formatting
+      working-directory: ./backend
+      run: cargo fmt --all -- --check
+```
+
+**Behavior**:
+- Runs `rustfmt` in check mode
+- Fails if code is not properly formatted
+- Runs in parallel with Clippy (faster feedback)
+- Uses strict formatting rules from `backend/rustfmt.toml`
+
+**How to Fix Format Issues**:
+```bash
+cd backend
+cargo fmt --all  # Auto-format all code
+git commit -am "style: auto-format code with rustfmt"
+```
+
+---
+
+### 3. Job Parallelization
+
+**Before**: Single monolithic job (sequential)
+
+**After**: Multiple parallel jobs
+
+```
+┌─────────────┐  ┌─────────────┐
+│   Format    │  │   Clippy    │  ← Run in parallel
+└──────┬──────┘  └──────┬──────┘
+       │                │
+       └────────┬───────┘
+                ▼
+       ┌─────────────┐
+       │    Build    │  ← Depends on format + clippy
+       └──────┬──────┘
+              ▼
+       ┌─────────────┐
+       │ Docker Build│  ← Depends on build
+       └─────────────┘
+```
+
+**Benefits**:
+- ⚡ Faster feedback (format + clippy run simultaneously)
+- 🎯 Clearer failure messages (separate jobs)
+- 📊 Better resource utilization
+- 🔄 Can run format/clippy without building
+
+---
+
+### 4. Docker Buildx Integration
+
+**New Job**: `docker-build`
+
+**Configuration**:
+- Uses `docker:cli` container
+- DinD service for isolated builds
+- Buildx for advanced features
+- Local caching for faster builds
+
+**Features**:
+```yaml
+services:
+  docker:
+    image: docker:dind
+    command: ["dockerd", "--host=tcp://0.0.0.0:2375", "--tls=false"]
+    options: >-
+      --privileged
+      -e DOCKER_TLS_CERTDIR=
+```
+
+**Buildx Commands**:
+```bash
+# Create builder with host networking
+docker buildx create --use --name builder --driver docker --driver-opt network=host
+
+# Build with caching
+docker buildx build \
+  --tag normogen-backend:${{ github.sha }} \
+  --tag normogen-backend:latest \
+  --cache-from type=local,src=/tmp/.buildx-cache \
+  --cache-to type=local,dest=/tmp/.buildx-cache-new,mode=max \
+  --load \
+  .
+```
+
+**Benefits**:
+- 🏗️ Multi-platform build support (can build for ARM, etc.)
+- 💾 Smart caching (faster subsequent builds)
+- 🔒 Isolated builds (DinD)
+- 🐳 Production-ready images
+- 📦 Versioned images (Git SHA tags)
+
+---
+
+## Workflow Structure
+
+### Job Dependencies
+
+```yaml
+format:     # No dependencies
+clippy:     # No dependencies
+build:      # needs: [format, clippy]
+docker:     # needs: [build]
+summary:    # needs: [format, clippy, build, docker]
+```
+
+### Execution Flow
+
+1. **Parallel Stage** (Fast feedback)
+   - Format check (~10s)
+   - Clippy lint (~30s)
+
+2. **Build Stage** (If quality checks pass)
+   - Build release binary (~60s)
+
+3. **Docker Stage** (If build succeeds)
+   - Build Docker image with Buildx (~40s)
+
+4. **Summary Stage** (Always runs)
+   - Report overall status
+   - Fail if any job failed
+
+---
+
+## CI Environment
+
+### Runner Details
+- **Location**: Solaria server
+- **Type**: Docker-based runner
+- **Label**: `docker`
+- **Docker Version**: 29.0.0
+- **Buildx Version**: v0.29.1
+
+### Docker-in-Docker Setup
+- **Service**: `docker:dind`
+- **Socket**: TCP endpoint (not Unix socket)
+- **Privileged Mode**: Enabled
+- **TLS**: Disabled for local communication
+
+### Why TCP Socket?
+
+Previous attempts used Unix socket mounting:
+```yaml
+volumes:
+  - /var/run/docker.sock:/var/run/docker.sock
+```
+
+This approach has issues:
+- ⚠️ Security concerns (host Docker access)
+- ⚠️ Permission issues
+- ⚠️ Not portable
+
+Current approach uses TCP:
+```yaml
+services:
+  docker:
+    image: docker:dind
+    command: ["dockerd", "--host=tcp://0.0.0.0:2375", "--tls=false"]
+```
+
+Benefits:
+- ✅ Isolated Docker daemon
+- ✅ No permission issues
+- ✅ Better security
+- ✅ Portable across runners
+
+---
+
+## Artifacts
+
+### Binary Upload
+```yaml
+- name: Upload binary artifact
+  uses: actions/upload-artifact@v4
+  with:
+    name: normogen-backend
+    path: backend/target/release/normogen-backend
+```
+
+### Docker Images
+Built images are tagged:
+- `normogen-backend:latest` - Latest build
+- `normogen-backend:{sha}` - Versioned by commit SHA
+
+**Note**: Pushing to registry is commented out (requires secrets)
+
+---
+
+## Usage
+
+### For Developers
+
+**Before Pushing**:
+```bash
+# Check formatting locally
+cd backend
+cargo fmt --all -- --check
+
+# Run clippy locally
+cargo clippy --all-targets --all-features -- -D warnings
+
+# Build to ensure it compiles
+cargo build --release
+```
+
+**If Format Check Fails**:
+```bash
+# Auto-fix formatting
+cargo fmt --all
+
+# Commit the changes
+git add .
+git commit -m "style: auto-format code"
+git push
+```
+
+**Triggering CI**:
+- Push to `main` or `develop`
+- Open/Update a PR to `main` or `develop`
+
+### For PR Review
+
+CI will automatically check:
+- ✅ Code is properly formatted
+- ✅ No Clippy warnings
+- ✅ Builds successfully
+- ✅ Docker image builds
+
+**All checks must pass before merging!**
+
+---
+
+## Troubleshooting
+
+### Format Check Fails
+
+**Error**: `code is not properly formatted`
+
+**Solution**:
+```bash
+cd backend
+cargo fmt --all
+git commit -am "style: fix formatting"
+```
+
+### Clippy Fails
+
+**Error**: `warning: unused variable` etc.
+
+**Solution**:
+1. Fix warnings locally
+2. Run `cargo clippy --all-targets --all-features -- -D warnings`
+3. Commit fixes
+
+### Docker Build Fails
+
+**Error**: `Cannot connect to Docker daemon`
+
+**Check**:
+- DinD service is running
+- TCP endpoint is accessible
+- No firewall issues
+
+**Solution**: The workflow uses privileged mode and proper networking - if it fails, check runner configuration.
+
+### Build Cache Issues
+
+**Error**: Cache growing too large
+
+**Solution**: The workflow uses a cache rotation strategy:
+```bash
+# Build with new cache
+--cache-to type=local,dest=/tmp/.buildx-cache-new,mode=max
+
+# Move new cache (removes old)
+mv /tmp/.buildx-cache-new /tmp/.buildx-cache
+```
+
+---
+
+## Future Enhancements
+
+### Ready to Enable (Commented Out)
+
+**1. Docker Registry Push**
+```yaml
+- name: Push Docker image
+  if: github.ref == 'refs/heads/main'
+  run: |
+    docker push normogen-backend:${{ github.sha }}
+    docker push normogen-backend:latest
+```
+
+**Requires**:
+- Set up container registry
+- Configure secrets: `REGISTRY_USER`, `REGISTRY_PASSWORD`
+
+**2. Integration Tests**
+```yaml
+test:
+  services:
+    mongodb:
+      image: mongo:7
+  steps:
+    - name: Run tests
+      run: cargo test --verbose
+```
+
+**3. Security Scanning**
+```yaml
+security:
+  steps:
+    - name: Run cargo audit
+      run: cargo audit
+```
+
+### Planned Enhancements
+
+- [ ] Add MongoDB for integration tests
+- [ ] Add code coverage reporting (tarpaulin)
+- [ ] Add security audit (cargo-audit)
+- [ ] Add deployment automation to Solaria
+- [ ] Add staging environment deployment
+- [ ] Add performance benchmarking
