Faster Editor Playback, GPU-Accelerated Exports & Windows Performance - Cap

Dramatically faster editor playback — Color conversion now happens entirely on the GPU, cutting data transfer by 62% and making scrubbing and playback feel significantly snappier. Frame caching and prefetch logic were also reworked so the editor stays responsive even on longer recordings.
GPU-accelerated exports — Exports are noticeably faster thanks to a new GPU rendering path with pipelined decoding. When GPU conversion isn't available, an optimized CPU fallback takes over automatically. Export size and time estimates are now much more accurate.
Windows playback performance — Switched to the native MediaFoundation decoder with zero-copy frame handling and preferred the Dx12 GPU backend, resulting in much lower latency during playback on Windows.
Prewarmed editor GPU pipeline — The rendering pipeline now initializes in the background at startup, so the editor is ready to play the moment you open it.
Better crop and padding rendering — Fixed an issue where padding and backgrounds rendered incorrectly when a crop region was applied.
Improved stability — Graceful shutdown handling to prevent crashes on exit, reliable camera window cleanup when recordings end, and better audio sync for long recordings.
