Common Agent Runtime (CAR) is a deterministic execution layer for AI
agents: models propose actions and the runtime validates, verifies, and
executes them. This package provides the pre-built Windows x64 binaries —
the CLI (car), the WebSocket server (car-server), and the StateBench
evaluation bridge (car-memgine-eval).
