fix: modernize Docker images to address security vulnerabilities and missing features

- Update base images to latest versions:
  - Distroless: debian11 -> debian12 (addresses CVE vulnerabilities in #22594)
  - Alpine: 3.20 -> 3.21 (latest stable)
  - All Debian variants: ensure bookworm (Debian 12)

- Add essential packages (fixes #4687):
  - git: now included in all non-distroless images
  - ca-certificates: for HTTPS connections
  - python3: in debian variant for node-gyp compatibility

- Add automated security workflow:
  - Weekly base image updates
  - Trivy vulnerability scanning
  - Automatic PR creation for updates
  - SARIF upload to GitHub Security

- Add comprehensive testing and publishing scripts:
  - test-all-images.sh: build and test all variants
  - publish-images.sh: multi-arch publishing with proper tagging

- Ensure distroless builds in CI (fixes #20414)
- Document all improvements and migration guide

This addresses multiple Docker-related issues including #22594, #20414, #4687, #3272, and improves overall Docker image security and usability.

+# Docker Image Improvements
+
+This document outlines the comprehensive improvements made to Bun's Docker images to address security vulnerabilities, missing features, and outdated base images.
+
+## Summary of Changes
+
+### 1. Security Updates
+
+#### Base Image Updates
+- **Distroless**: Updated from `debian11` to `debian12` (bookworm) - Addresses CVE vulnerabilities reported in #22594
+- **Alpine**: Updated from `3.20` to `3.21` - Latest stable Alpine release with security patches
+- **Debian/Debian-slim**: Ensured using `bookworm` (Debian 12) consistently
+
+#### Automated Security Workflow
+- Added `.github/workflows/docker-security.yml` for:
+  - Weekly automated base image updates
+  - Vulnerability scanning with Trivy
+  - Automatic PR creation for security updates
+  - SARIF upload to GitHub Security tab
+
+### 2. Feature Additions
+
+#### Essential Packages
+Added commonly requested packages to all non-distroless images:
+- **git**: Addresses #4687 - Required for git-based npm dependencies
+- **ca-certificates**: Ensures HTTPS connections work properly
+- **python3** (debian only): For node-gyp compatibility
+
+### 3. Build and Publishing Improvements
+
+#### New Scripts
+- **`test-all-images.sh`**: Comprehensive testing script that:
+  - Builds all Docker variants
+  - Tests bun/bunx commands
+  - Verifies JavaScript execution
+  - Checks package installation
+  - Runs security scans
+  
+- **`publish-images.sh`**: Production-ready publishing script that:
+  - Supports multi-architecture builds (amd64/arm64)
+  - Handles semantic versioning tags
+  - Provides dry-run capability
+  - Manages all variant suffixes correctly
+
+### 4. Issues Addressed
+
+The following issues are resolved or improved by these changes:
+
+- **#22594**: HIGH vulnerabilities in Debian images - Fixed by updating base images
+- **#20414**: Distroless images outdated - Fixed by ensuring distroless is built in CI
+- **#4687**: Missing git in Docker images - Fixed by adding git to all images
+- **#3272**: CVEs in Docker images - Addressed via base image updates and security scanning
+- **#17463**: Shell commands issues in distroless - Documented as expected behavior
+- **#18325**: bunx not available in Alpine - Verified symlink creation
+
+## Docker Image Variants
+
+### 1. Debian (Full)
+- Base: `debian:bookworm`
+- Includes: git, curl, python3, ca-certificates
+- Use case: Full compatibility, development environments
+
+### 2. Debian Slim
+- Base: `debian:bookworm-slim`
+- Includes: git, ca-certificates
+- Use case: Production with minimal overhead
+
+### 3. Alpine
+- Base: `alpine:3.21`
+- Includes: git, ca-certificates, libgcc, libstdc++
+- Use case: Smallest image size with package management
+
+### 4. Distroless
+- Base: `gcr.io/distroless/base-nossl-debian12`
+- Includes: Only Bun binary
+- Use case: Maximum security, minimal attack surface
+- Note: No shell, no package manager - purely for running Bun applications
+
+## Usage Examples
+
+### Basic Usage
+```dockerfile
+# Development - full features
+FROM oven/bun:latest
+
+# Production - smaller size
+FROM oven/bun:slim
+
+# Minimal - smallest size with package manager
+FROM oven/bun:alpine
+
+# Maximum security - no shell
+FROM oven/bun:distroless
+```
+
+### With Git Dependencies
+```dockerfile
+FROM oven/bun:slim
+WORKDIR /app
+COPY package.json bun.lockb ./
+# Git is now available for git-based dependencies
+RUN bun install --frozen-lockfile
+COPY . .
+CMD ["bun", "run", "start"]
+```
+
+### Multi-stage Build
+```dockerfile
+# Build stage
+FROM oven/bun:latest AS build
+WORKDIR /app
+COPY package.json bun.lockb ./
+RUN bun install --frozen-lockfile
+COPY . .
+RUN bun run build
+
+# Production stage - distroless for security
+FROM oven/bun:distroless
+WORKDIR /app
+COPY --from=build /app/dist ./dist
+COPY --from=build /app/node_modules ./node_modules
+ENTRYPOINT ["bun", "dist/server.js"]
+```
+
+## CI/CD Integration
+
+### GitHub Actions
+The release workflow now:
+1. Builds all variants including distroless
+2. Pushes to Docker Hub with proper tags
+3. Runs security scans
+4. Updates base images automatically
+
+### Local Testing
+```bash
+# Test all images
+cd dockerhub
+./test-all-images.sh
+
+# Test with specific version
+./test-all-images.sh v1.2.22
+
+# Build and publish (dry run)
+./publish-images.sh
+
+# Build and publish (actual push)
+PUSH_IMAGES=true BUN_VERSION=v1.2.22 ./publish-images.sh
+```
+
+## Security Best Practices
+
+1. **Use distroless for production** when possible - smallest attack surface
+2. **Regular updates** - Automated weekly base image updates via GitHub Actions
+3. **Vulnerability scanning** - Integrated Trivy scanning in CI
+4. **Minimal packages** - Only essential packages included
+5. **Non-root user** - All images run as `bun` user (UID 1000)
+
+## Migration Guide
+
+### From Old Images
+If you're using older Bun Docker images:
+
+1. **Update base image tags** in your Dockerfiles
+2. **Remove git installation** steps - git is now included
+3. **Check for CVE warnings** - New images address known vulnerabilities
+4. **Test distroless** - Consider migrating to distroless for production
+
+### Breaking Changes
+- Distroless now uses Debian 12 instead of Debian 11
+- Alpine updated to 3.21 (check for Alpine-specific compatibility)
+
+## Future Improvements
+
+Potential future enhancements:
+- [ ] Add HEALTHCHECK instructions
+- [ ] Create debug variants with additional tools
+- [ ] Add Windows container support
+- [ ] Implement image signing with cosign
+- [ ] Add SBOM (Software Bill of Materials) generation
+
+## Contributing
+
+To contribute to Docker image improvements:
+1. Test changes with `./test-all-images.sh`
+2. Update this documentation
+3. Ensure CI passes
+4. Submit PR with clear description of changes
+
+## Support
