Same place the extra force comes from if I use a first-class lever to lift a heavy rock. There is no "conservation of force" law in physics.

It seems from your explanation that you might be able to put a carpet-treaded wheel underneath the mecanum wheel at a 45 degree angle and get greater torque at its axle than you put into the original mecanum wheel.

Of course I could. Or I could save myself all that trouble and use a gearbox instead :-)
Or I could just use the circumference of a small standard wheel to drive the circumference of a larger standard wheel. This would create greater torque on the larger wheel than was input to the smaller wheel.

Then use that torque to drive another mecanum wheel driving another carpet wheel and keep multiplying forces ad infinitum.

Yes, you could do that. Just like I could use the "load" end of one first-class lever to drive the "effort" end of a another second-class lever, ad infinitum.

There is no "conservation of torque" law in physics either.

It's apparent that something is wrong with your model.

Nope.
