Introduce a set of test tools and demo assets for an AntMan-style scaling effect: - Add AntManScaleController: handles smooth scale transitions (absolute/relative modes), pivot preservation, queued toggles and events. - Add GhostTrailEmitter and GhostTrailGhost: spawn fading ghost meshes (supports skinned mesh baking, material fallback, lifetime and pooling limit). - Add GKTInventoryScaleToggle: inventory-gated input wrapper to toggle scale with optional Ctrl bypass and auto reference resolution. - Add AntManTestSceneBootstrap and TestBootstrap prefab to quickly construct a test scene (cube, light, camera) with components configured. - Add AntManScaleTest scene and related prefab/meta files, plus .vsconfig for Unity workload. - Update SampleScene LFS pointer (scene file checksum/size). These changes provide a reusable demo and components to test scaling visuals and interactions during development.
