- 9.1: allocate shared Depth32Float depth texture + view in Renderer,
sized to the initial surface (create_depth_texture helper, reusable
for the Phase 4.4 resize); Renderer::new now takes width/height.
- 9.2: attach depth_stencil_attachment (clear 1.0 / store) to both the
low-level render and high-level render_scene passes.
- 9.3: every pipeline declares a matching DepthStencilState (write true,
compare Less) via the shared DEPTH_FORMAT constant (D1).
