Editor/Drivers/SpecializedAssetDriver.cs

Editor utility class that provides helper methods for creating or inspecting simple asset files for sprites, shader graphs, and hotspot rect definitions. Each method optionally creates directories, writes minimal JSON/text templates to the given path, and returns a ToolOutcome with metadata.
