v1.1.0

• New package RecursiveAI.OneShader.Tool: the oneshader command-line compiler (a .NET tool, and a NativeAOT single-file binary with dotnet publish -r <rid>). It takes DXC's core flags (-T, -E, -D, -I, -Fo, -spirv, -O0..-O3, -Zpr/-Zpc, -HV 2021, -WX) plus --target spirv|msl|wgsl (repeatable), --all-entries, --reflect <file.json> and --depfile <file>. Diagnostics print as file(line,col): error OSHnnnn: message; exit code 0, 1 for compile errors, 2 for command-line errors.
• Pipeline layout helpers (OneShader.Layouts): plain data, no graphics API behind it, that turns a shader into what a renderer creates. EntryLayout (from reflection with EntryLayout.TryCreate, or the generated Sprite.VSMain.Layout) and PipelineLayout.TryCreate merge entry points into bind groups with combined stage visibility and push-constant blocks, returning conflicts as a LayoutError value. ToVulkan() gives descriptor set layouts, push-constant ranges and vertex input with numeric VkDescriptorType/VkShaderStageFlagBits/VkFormat values; TryToMetal() gives per-stage buffer, texture and sampler indices, the setBytes slot and MTLVertexDescriptor data; TryToWebGpu() gives bind group layout entries with the WebGPU enum strings, push constants as a uniform buffer at the reserved group and binding, and vertex buffer layouts. Generated classes gain Layout on every entry point and Pipeline (vertex + pixel, or one compute entry point) on the file.
• Wave (subgroup) and quad intrinsics on all three targets: WaveGetLaneCount/Index, WaveIsFirstLane, WaveActiveAnyTrue/AllTrue/AllEqual/Ballot/Sum/Product/Min/Max/BitAnd/BitOr/BitXor/CountBits, WavePrefixSum/Product/CountBits, WaveReadLaneAt/First and QuadReadAcrossX/Y/Diagonal/QuadReadLaneAt on 32-bit int, uint and float scalars and vectors. SPIR-V uses GroupNonUniform* as DXC does, MSL simd_*/quad_*, WGSL the subgroups feature (enable subgroups;; not in vertex shaders). WaveMatch and WaveMultiPrefix* are an error (OSH0350). Reflection gains EntryPointInfo.SubgroupOperations (Vulkan's VkSubgroupFeatureFlagBits values), EntryPointInfo.UsesSubgroups and ShaderReflection.UsesSubgroups; EntryLayout/PipelineLayout/PipelineLayoutInfo/MetalPipelineLayout carry SubgroupOperations, WebGpuPipelineLayout.RequiredFeatures lists subgroups, and generated entry classes get a SubgroupOperations constant. BuiltIn gains SubgroupLocalInvocationId and SubgroupSize.
• Reflection: ResourceInfo.ImageFormat records the [[vk::image_format]] name of a storage texture (the serialized resource record gets an optional format attribute, written only when set).
