The sawtooth and square patterns had a fixed 1000 sample pulse width. Both now take a period, and the square pattern a duty cycle, from the GUI, a preset or the web API, with the period shown in seconds beside the sample count. A period of zero divides by zero in the sawtooth and wraps the unsigned sample counter in the square pattern, giving a cycle of four billion samples, so it is refused at every entrance: a minimum of one on the spin box, a clamp when an older or hand edited preset is read, a clamp on the web API, and a clamp in the worker for anything that reaches it another way. The duty cycle is held to 0 to 100 the same way. Also fixes the worker's timer. It is now parented to the worker so that it moves to the worker thread with it, and it runs between startWork and stopWork rather than from construction. TestSourceInput::stop() runs in another thread, and Qt will not stop a timer from one, so the stop is asked of the worker and waited for. The m_running flag it replaces is gone, along with the test of it in every tick. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
