Add Clumsy plugins and dual-vehicle fleet sync demo.

Restructure into DiffWheel/MultiWheel folders, add DiffWheelC and MultiWheelC with MovementTests, FleetRemote multi-vehicle manual sync, deploy templates, and documentation. Update dependency paths to D:\MDCS\Release and mirror motor feedback in MotorRoutine for simulation.
