Safari/iOS memory fixes and platform-specific loader tuning for the iOS 26 GPU crash.

  • Improved Draco and KTX2 worker pools are limited to a single thread on iOS to keep WebKit memory stable on iOS 26 devices.
  • Improved Shared KTX2 detection now scopes per platform so desktop browsers keep their parallelism.
  • Fixed Cached GLTF scenes, textures, and parser registries are released immediately after model swaps, preventing Safari desktop/iOS 26 crashes.
  • Fixed Abort listeners and converted materials are disposed right after loads so cancelled requests can’t leak GPU resources and trip the iOS 26 GPU watchdog.
