• ✅ Docker build testing
• ✅ Automated PR comments with results
• ✅ Coverage reporting (Codecov integration)

CD - Development (cd-development.yml)

• ✅ Quick test suite for fast feedback
• ✅ Automated builds on develop branch
• ✅ Multi-platform images (AMD64, ARM64)
• ✅ Publish to GitHub Container Registry
• ✅ Development release creation
• ✅ Deployment manifest generation

CD - Release (cd-release.yml)
