Unload system RAM after video generation is complete

Framepack uses most of my 32GB system ram but doesn't unload it when the video is done generating. Not sure if this puts unnecessary stress on my ram (does it?) but wouldn't it be better to release the ram when finished with a generation? You can see the drop when the ram was released only when I closed out Framepack.


No file, test, or entry point is named. Reproduce a video generation while monitoring system RAM, then locate the generation-completion and cleanup paths to determine which resources remain held after completion. Done means memory is released without requiring FramePack to close, with a regression test or documented verification of the behavior.
