New [ExecuteAlways] component that renders the skybox (or an optional override material) into a custom reflection cubemap and refreshes DynamicGI so smooth/metallic materials reflect the sky without a baked LightingData asset. Uses a deferred apply plus a synchronous warm-render so the ambient probe resolves after domain reload; runs the reflection capture as a stripped CameraType.Reflection to avoid the URP MIP-bind error. Exposes reflection intensity (0..4) and optional ambient override.
