Resolves build failure caused by PEP 668 "externally-managed-environment"
protection in Python 3.11+. The --break-system-packages flag is safe to
use in this containerized development environment as it won't affect the
host system. This allows pip to install development tools (black, flake8,
isort) globally within the container as intended.
Fixes devcontainer creation error that was preventing environment setup.
- Configure Claude Code optimized devcontainer with Python support
- Add Python development tools (black, flake8, isort) to Dockerfile
- Include VS Code extensions for Python and workflow development
- Add firewall script for secure development environment
