Docker Image Build Pipeline with OpenSSL Optimization

[perigrin]

User Story

Implement Docker image build pipeline using TDD for Solanum IRCd and Atheme services.
Write tests that validate OpenSSL optimization for AMD EPYC processors, proper dependency
installation, and successful compilation. Ensure images are built with security hardening
and performance optimizations.

Requirements:
- Create Dockerfile.solanum with OpenSSL acceleration
- Create Dockerfile.atheme with PostgreSQL support  
- Implement multi-stage builds for optimal image size
- Validate AMD EPYC specific optimizations

Expected Output

• Dockerfile.solanum - Optimized Solanum IRCd container with OpenSSL acceleration
• Dockerfile.atheme - Atheme services container with PostgreSQL support
• tests/test_docker_builds.py - Container build validation tests
• scripts/build-images.sh - Automated build script with optimization flags
• docs/container-architecture.md - Container design and optimization documentation
• Built and tagged container images ready for deployment

Acceptance Criteria

• Write failing tests for Docker image build validation
• Create Dockerfile.solanum with OpenSSL optimizations for AMD EPYC
• Create Dockerfile.atheme with PostgreSQL client libraries
• Implement multi-stage builds to minimize final image size
• Tests validate successful compilation of Solanum IRCd
• Tests verify OpenSSL acceleration features are enabled
• Tests confirm Atheme builds with proper database connectivity
• Security scanning passes for both images
• Images run successfully in test containers
• Build process completes in under 10 minutes
• All tests pass with comprehensive coverage

Context

Docker images form the core runtime environment for the IRC network. These optimized images will run on Fly.io's AMD EPYC infrastructure, requiring specific OpenSSL optimizations for maximum SSL/TLS performance. This step ensures reliable, secure, and performant container deployments.
