Update configuration in .claude/CLAUDE.md with expanded stack (Python, R, bash), detailed linting/test commands, and stricter bash safety rules (no uncontrolled eval, prefer shellcheck). Adjust MCP servers to use configurable port 8888 instead of hardcoded 1248, and improve code formatting in agent_lm.py and server.py. Update README.md with concrete repository URL for cloning/subtree operations, and add missing tool requirements (aichat, jq, argc).
