- Introduced `shadow_ray_params` to simplify ray origin and cull mask management.
- Shifted shadow ray origins to TLAS-relative space for improved precision and consistency, especially for cockpit rendering.
- Refactored cascade bind functions, adding `shadow_cascade_params_bind_deferred()` for consolidated offset/count handling in deferred lighting.
- Expanded TLAS to include cockpits and additional object types, ensuring parity with rasterized shadows.
- Introduced per-instance cull masks to address cockpit self-shadowing issues.
- Improved Vulkan depth isolation for cockpit rendering via backup/restore mechanism, ensuring correct depth sampling in later passes.
- Extracted reusable helper functions for cockpit rendering state logic.
