Move DefaultNetworkPrefabs.asset out of Assets/Settings back to the Assets root (where NGO expects it), and fix the PlaySceneWindow domain-reload toggle to read and write EnterPlayModeOptions correctly.
Move editor scripts to Assets/Scripts/Editor (PlaySceneWindow, SceneCollection),
move DefaultNetworkPrefabs and the Main Camera custom blends asset into
Assets/Settings, and shelve the unused HeroCutout shader/include under
Assets/Unused. Rename the Chameleon background texture, delete the obsolete
DefaultParentForEditor script and New Lighting Settings asset, add a The Room
SceneCollection asset, and drop the redundant Assets menu entry from the
StraightenKnees tool.
