The MotionVectors pass (drawn by HTrace and URP against the real camera
depth buffer) was stock URP: no cutout clip and ZWrite on, so it wrote
the wall depth back into the hole after opaques. The skybox then failed
the depth test there (black disc) and all screen-space effects
(SSAO/GI) shaded the hole with the occluded wall's depth.
The pass now runs ApplyHeroCutout before URP's fragment entry point.
ObjectMotionVectors.hlsl forces its own entry via include_with_pragmas,
so the pragmas are declared explicitly and the file is plain-included.
Complements the earlier GBuffer clip; XR MV pass and ShadowCaster stay
stock on purpose. Includes render-queue churn on the occluder material.
