Regression screenshots

regression_test.sh compares the last screenshot dumped during its 600-frame run (frame 500) against these images.

The Jagniccc baseline includes the live PIT1 timing readout introduced by #1047. Its source (JaguarDemos/jagniccc2000/jagniccc.S, again loop) subtracts PIT1 reads to display rendering and elapsed milliseconds. The old baseline showed zeros because reads returned the timer reload value. The update changes 86 pixels within (80,28)–(211,34); the scene and frame counter are unchanged. Linux ARM64 and macOS ARM64 CI captures were pixel-identical.
