Fixes timing scopes to more accurately represent a per-frame main thread breakdown, and prevents spikes when GC is executed. - **GcPause** - New separate timing scope showing time spent in GC per frame - GC pause time is subtracted from all other scopes, so each scope now only tracks its own code execution and no longer includes GC overhead - e.g. when GC occurs during the audio scope, the audio scope no longer spikes to 20ms - **AudioMixingThread** removed from the main scopes - Runs on a separate thread, so its timings are effectively meaningless in the main thread view - All other scopes are main thread only - No longer relevant given the audio optimisation work done over the past months - **Scene** scope removed - Didn't make much sense as it was an aggregate wrapping many other timing scopes - Replaced with a finer `Update` scope that tracks `Component.FixedUpdate`/`Update` - **Editor** scope no longer shows in-game - Scopes reschuffled - e.g. verlet rope physics traces are now tracked under the physics scope - Audio occlusion queries are now tracked under the audio scope https://files.facepunch.com/lolleko/2026/March/02_12-59-QuixoticMarten.png
