- add standalone pass asset factories for camera frame stages\n- let managed pipeline assets declare stage pass asset keys\n- make universal renderer data explicitly own the builtin shadow caster stage
- expose directional shadow planning settings on camera request context\n- let the managed universal asset override planner defaults\n- recompute native directional shadow requests only when settings change
- add managed RenderStateBlock authoring types and wire them through DrawingSettings
- let RenderObjectsRendererFeature author depth and stencil overrides for scene draws
- apply scene draw render state overrides inside builtin forward pipeline and document the stage plan
- add ScriptableRenderContext.DrawSkybox as a public main-scene draw primitive
- route default RecordScene and DrawSkyboxPass recording through explicit draw calls
- expose the new DrawSkybox API in the scriptable render context probe
- let DrawingSettings carry an optional shaderPassName across managed and native scene draw APIs
- allow RenderObjectsRendererFeature to author explicit ForwardLit or Unlit scene draws
- exercise the new scene draw pass selection seam in the project render pipeline probe
- add a managed DrawingSettings seam for scene draw authoring
- let builtin forward scene draws use an override material when provided
- wire DrawObjectsPass and RenderObjectsRendererFeature through the new settings
- carry MeshRenderer renderLayer through scene extraction into VisibleRenderItem
- extend native and managed FilteringSettings with renderLayerMask support
- let RenderObjectsRendererFeature author layer-filtered object draws
- add a core RenderQueueRange helper for managed scene draw filtering
- let FilteringSettings and RenderObjectsRendererFeature consume queue ranges directly
- wire the new authoring path into probes and project-side usage
- bridge renderer list descriptors into ScriptableRenderContext scene draw calls
- reuse DrawObjectsPass across Universal and project custom renderers
- add RenderObjectsRendererFeature for package-level object draw extension
