A Rust-based bridge that connects the veecle-os runtime with an external vehicle simulation system. It enables real-time control and sensor data exchange through a Unix socket using a JSON protocol.

This simulator acts as an interface layer that:

• Receives vehicle control commands (throttle, brake, steering) from veecle-os
• Forwards these commands to an external simulation via Unix socket
• Receives sensor data (primarily speed) from the simulation
• Publishes sensor readings back to the veecle-os runtime

veecle-os Runtime <---> Simulator Bridge <---> External Simulation
                         (this actor)         (/opt/simulation.sock)

The bridge communicates with the external simulation using:

• Transport: Unix domain socket at /opt/simulation.sock
• Format: Newline-delimited JSON
• Direction: Bidirectional (control commands out, sensor data in)

• Throttle: Position control (0.0 = closed, 1.0 = fully open)
• Brake: Pressure control (0.0 = released, 1.0 = maximum pressure)
• Steering: Angle control (-1.0 = full left, 0.0 = center, 1.0 = full right)
• ParkingBrake: Engagement control (0.0 = released, 1.0 = fully engaged)

• Speed: Vehicle speed in kilometers per hour (km/h)
