grantmartin2002-oss 6bb5a5709b fix(darwin): preserve FloatingPanel level, clean up sendEvent
- Fix FloatingPanel level override: skip setting default WindowLevel
  when NSPanel has FloatingPanel=true, preserving setFloatingPanel
  behavior
- Clean up sendEvent override comments
- Fix typo in changelog (auxillary -> auxiliary)
