Update 0.0.3: smoother loading and stability — Tied to the Beat Steam update #2097165

This update focuses on loading behavior and stability. - The loading bar shown when returning to the menu now reflects the real progress of the reload. Previously it filled up early and stayed at 100%, which made the game look frozen. - Reduced the frame hitch that could happen while a run starts, when visual effects are prepared behind the curtain. The pause is around 20% shorter, with no visual changes. - Fixed a rare issue where the game could stay at very low FPS after recovering from a crash during a run. - Fixed an internal error that caused a failed file request on some runs. Thanks for playing and for reporting issues.
