The fill valve (ball valve UK) is siezed or clogged.

As the water level rises, the float-ball rises and closes the valve when the water reaches the proper level.

How a toilet 'knows' when to stop filling the tank?

Toilets use float valves. These are air filled balls that float on the water, as the cistern fills with water the ball floats higher. The ball is attached to an arm connected to a valve, when the ball reaches a predefined level the valve closes, shutting off the water to the cistern.

Why would a toilet that has been working properly just stop flushing even though the tank and the bowl both fill up?

there can be many reasons and I will say my thoughts on just a few. 1. your toilet trap of the bowl is clogged with debris (toys, balls, etc) to fix = snake out toilet bowl or if necessary pull toilet bowl and snake backwards threw trap. 2. your tank flush flapper is closing to soon or your tank water level is not at right height to fix = change flapper or adjust water level height 3. your toilet arm before the vent is plugged because of back grade or debris clinging to the side of the drain pipe to test = pull toilet and run toilet water supply full on down threw toilet flange and see if any back flow. 4. your toilet main line is clogged from backgrade,roots,damaged pipe,etc but will let other fixtures slowly drain to test = camera toilet line from toilet flange out to street or septic or if no camera available then fill tub full and lav full and drain both at the same time and look at your lowest fixture trap to see if any back flow exists or open clean outs and if possible to see water flow .
