🐳 feat: implement Docker multi-stage build with caching optimization
Added Docker build infrastructure: - Multi-stage build (builder, cache, production) - Dependency hashing for cache invalidation - GNU tar support for cache compatibility - Production and development Dockerfiles - Docker Compose for local development Build Optimization: - Dependency-based cache keys - Layer caching strategy - Cross-platform compatibility - Gitea Actions cache integration Files Added: - docker/Dockerfile.build - Build environment - docker/Dockerfile.prod - Production image - docker/Dockerfile.prod.template - Template-based generation - docker-compose.yml - Development setup - scripts/calculate-deps-hash.sh - Cache key calculation - scripts/test-docker-cache.sh - Cache testing Generated by Mistral Vibe.
