OrdinaryShade v0.1.0a8

OrdinaryShade 0.1.0a8

Add typed GPU primitives used by resident geometry and voxel-output pipelines.

• Fixed-size workgroup arrays through osh.shared(osh.array(type, count)), with GLSL and WGSL lowering. Applications provide initialization and barriers.
• Explicit buffer_float32_atomic_add capability and scalar storage-buffer osh.atomic_add support in GLSL. Reject missing capabilities, mismatched scalar types, non-buffer targets, and unsupported WGSL compilation.
• Ray-query triangle candidate confirmation through query.confirm_intersection().

Floating-point atomic addition requires the corresponding Vulkan device features;
it does not enable shared-memory or image atomics. Sum rounding depends on GPU
execution order. This remains a pre-alpha compiler release.
