Add Kubernetes-optimized Dockerfiles alongside original Docker Compose versions:
**New K8s Dockerfiles:**
- python/Dockerfile.k8s.server - Non-root, graceful shutdown
- python/Dockerfile.k8s.mcp - Lightweight K8s optimized
- python/Dockerfile.k8s.agents - Production-ready agents
- archon-ui-main/Dockerfile.k8s.production - Non-root nginx
**CI/CD Updates:**
- Modified .gitea/workflows/build-images.yml for serial execution
- Builds 8 images: 4 Docker versions + 4 K8s versions
- Tags: docker-latest/docker-{sha} and k8s-latest/k8s-{sha}
- Serial execution prevents memory overload
**K8s Manifest Updates:**
- Updated k8s-manifests-complete.yaml to use k8s-latest tags
- Added securityContext for non-root execution
- Added terminationGracePeriodSeconds for graceful shutdown
- Applied container security best practices
**Optimizations:**
- Non-root users (UID/GID 1001) for all services
- Proper signal propagation (graceful shutdown)
- Removed HEALTHCHECK (K8s uses probes)
- Cache cleanup for smaller images (~10% reduction)
- Production-only builds (no test files)
**Documentation:**
- DOCKER_K8S_BUILD_STRATEGY.md - Complete usage guide
- DOCKERFILE_K8S_IMPROVEMENTS.md - Technical analysis
Original Dockerfiles remain unchanged for Docker Compose compatibility.

# MCP Service - Kubernetes optimized build

|
# Lightweight HTTP-based microservice optimized for K8s
|
|
# Optimizations:
|
|
# - Non-root user for security
|
|
# - Proper signal propagation for graceful shutdown
|
|
# - No HEALTHCHECK (K8s uses liveness/readiness probes)
|
|
# - Cache cleanup for smaller image size
