Skybox/SkyLight are now Actor-carried components instead of resident
global settings, matching UE where SkyAtmosphere/SkyLight/fog are
Actors added from Place Actors and configured in Details.
- New SkyboxComponent (active + envPath asset slot) and SkyLightComponent
(active + ambientColor); first-active entity wins per frame
- SceneRenderer collects env from components into FrameSceneData
(DrawSkybox/envPath/ambient); Renderer performs delta sync - env
reloads only when the resolved path changes, neutral fallback when
empty or unloadable
- App-side env plumbing removed: kEnvPaths table and getEnvIndex/
setEnvIndex callbacks deleted; StatsPanel keeps ClearColor + debug
view, env params move to Details
- Serializer: scene-level Settings stores ClearColor only; env
components serialize per entity; legacy v1 scenes (Environment header
+ Settings.AmbientColor/DrawSkybox) auto-migrate into an Environment
entity on load for visual parity
- Inspector: Skybox/Sky Light sections with .hdr asset slot dropdown
and Add Component entries; Outliner "+ Create" popup offers
Empty/Light/Camera/Environment
