Detailed Description

Transition that fires automatically after a specified delay.

Useful for adding timeout behavior to any state without requiring WaitStateBase.

The timer starts when the source state is entered and stops when exited. If the timer expires while in the source state, the transition is taken.

Example usage:

auto* timeoutTransition = new TimeoutTransition(5000, errorState);
normalState->addTransition(timeoutTransition);
