TRAX: toggle refreshes the status light on play/pause, terse scrolling error on failure, fixed quiet volume (0.5), ITraxPlayer seam. Deadlocked test fixed via RunAsync (was GetAwaiter().GetResult on the UI thread). 416 pass / 1 known env flake. Refs: https://learn.microsoft.com/en-us/dotnet/standard/asynchronous-programming-patterns/async-programming-model-tap#dont-block-on-async-code (Unit: trax toggle)
