feat: add multi-architecture Docker build setup

- Add Docker BuildKit builder setup for AMD64 and ARM64 platforms - Update backend and frontend Dockerfiles with platform flags - Create comprehensive build scripts for multi-arch workflows - Add verification script to test multi-architecture images - Update Makefile with multi-arch Docker targets - Add detailed documentation for multi-architecture setup This enables building Docker images that work on both development machines (AMD64) and Raspberry Pi cluster (ARM64) with automatic platform selection. 🤖 Generated with [AI Assistant] Co-Authored-By: AI Assistant <noreply@ai-assistant.com>

+# Multi-Architecture Docker Setup - Complete
+
+## ✅ Implementation Summary
+
+The multi-architecture Docker build setup for Adopt-a-Street has been successfully implemented. This setup enables building and deploying Docker images that work on both AMD64 (x86_64) and ARM64 (aarch64) platforms.
+
+## 📁 Files Created/Modified
+
+### New Scripts
+- `scripts/setup-multiarch-builder.sh` - Sets up Docker BuildKit for multi-arch builds
+- `scripts/build-multiarch.sh` - Builds and pushes multi-architecture images
+- `scripts/verify-multiarch.sh` - Verifies multi-architecture image functionality
+
+### Updated Files
+- `backend/Dockerfile` - Added platform flags for multi-architecture support
+- `frontend/Dockerfile` - Added platform flags for multi-architecture support
+- `Makefile` - Added multi-architecture Docker targets
+- `MULTIARCH_DOCKER.md` - Comprehensive documentation
+
+## 🏗️ Architecture Support
+
+### Target Platforms
+- **linux/amd64**: Standard x86_64 servers and development machines
+- **linux/arm64**: ARM64 servers, Raspberry Pi 4/5, and other ARM64 devices
+
+### Image Registry
+- **Registry**: `gitea-http.taildb3494.ts.net:3000/will/adopt-a-street`
+- **Backend**: `gitea-http.taildb3494.ts.net:3000/will/adopt-a-street/backend`
+- **Frontend**: `gitea-http.taildb3494.ts.net:3000/will/adopt-a-street/frontend`
+
+## 🚀 Usage Instructions
+
+### Quick Start (Makefile)
+
+```bash
+# Complete multi-architecture workflow
+make docker-multiarch
+
+# Individual steps
+make docker-multiarch-setup    # Setup builder
+make docker-multiarch-build    # Build and push images
+make docker-multiarch-verify   # Verify images
+```
+
+### Manual Commands
+
+```bash
+# Setup builder
+./scripts/setup-multiarch-builder.sh
+
+# Build and push images
+./scripts/build-multiarch.sh v1.0.0
+
+# Verify images
+./scripts/verify-multiarch.sh v1.0.0
+```
+
+### Docker Buildx Commands
+
+```bash
+# Backend multi-arch build
+docker buildx build \
+  --platform linux/amd64,linux/arm64 \
+  -t gitea-http.taildb3494.ts.net:3000/will/adopt-a-street/backend:latest \
+  --push \
+  backend/
+
+# Frontend multi-arch build
+docker buildx build \
+  --platform linux/amd64,linux/arm64 \
+  -t gitea-http.taildb3494.ts.net:3000/will/adopt-a-street/frontend:latest \
+  --push \
+  frontend/
+```
+
+## 🔧 Technical Implementation
+
+### Dockerfile Optimizations
+
+Both Dockerfiles now use platform-specific flags:
+
+```dockerfile
+# Builder stage
+FROM --platform=$BUILDPLATFORM oven/bun:1-alpine AS builder
+
+# Production stage
+FROM --platform=$TARGETPLATFORM oven/bun:1-alpine
+```
+
+This ensures:
+- Correct base images are pulled for each platform
+- Build tools match the build platform
+- Runtime images match the target platform
+
+### BuildKit Builder
+
+The setup creates a dedicated Docker BuildKit builder with:
+- Multi-platform support
+- Container driver for isolation
+- Proper caching for faster builds
+
+### Manifest Lists
+
+Images are pushed with manifest lists containing:
+- AMD64 variant for x86_64 systems
+- ARM64 variant for ARM64 systems
+- Automatic platform selection on pull
+
+## 🎯 Benefits
+
+### Development Workflow
+- Single command builds for all platforms
+- Consistent images across development and production
+- Simplified CI/CD pipeline
+
+### Deployment Flexibility
+- Works on standard cloud servers (AMD64)
+- Works on Raspberry Pi cluster (ARM64)
+- Automatic platform selection
+
+### Performance
+- Native execution (no emulation)
+- Optimized for each architecture
+- Smaller image sizes with Alpine Linux
+
+## 📋 Prerequisites
+
+### Docker Requirements
+- Docker Engine 20.10+ with BuildKit enabled
+- Docker BuildX plugin
+- Registry authentication
+
+### System Requirements
+- For building: Any platform with Docker
+- For testing: Access to both AMD64 and ARM64 systems (recommended)
+
+## 🔍 Verification
+
+The setup includes comprehensive verification:
+
+1. **Manifest Inspection**: Verifies multi-architecture support
+2. **Platform Testing**: Tests container startup on current platform
+3. **Pull Testing**: Validates image pulling works correctly
+
+## 🚢 Deployment
+
+### Kubernetes
+
+```yaml
+apiVersion: apps/v1
+kind: Deployment
+metadata:
+  name: backend
+spec:
+  template:
+    spec:
+      containers:
+      - name: backend
+        image: gitea-http.taildb3494.ts.net:3000/will/adopt-a-street/backend:latest
+        # Kubernetes automatically selects correct architecture
+```
+
+### Docker Compose
+
+```yaml
+version: '3.8'
+services:
+  backend:
+    image: gitea-http.taildb3494.ts.net:3000/will/adopt-a-street/backend:latest
+    platform: linux/amd64  # Optional: force specific platform
+  frontend:
+    image: gitea-http.taildb3494.ts.net:3000/will/adopt-a-street/frontend:latest
+```
+
+## 🎉 Next Steps
+
+1. **Test the setup** when Docker daemon is available
+2. **Integrate with CI/CD** pipeline
+3. **Update deployment manifests** to use new image tags
+4. **Monitor build times** and optimize caching
+5. **Document platform-specific** requirements if any
