- Rename texture/dtor.md to destructor.md per template spec - Remove duplicate non-hyphenated fence docs (getnativehandle.md, issignaled.md, getcompletedvalue.md) - Fix template field issues: - swap-chain, command-queue: 类型 now uses 'class (abstract)' - sampler: 头文件 now uses full path 'XCEngine/RHI/RHISampler.h' - types: 类型 fixed from 'structs' to 'struct' - enums: 类型 fixed from 'enums' to 'enum class' - Fix include paths in command-queue and pipeline-layout code examples - Create missing constructor/destructor docs for 11 classes: buffer, texture, shader, device, command-list, command-queue, fence, sampler, swap-chain, pipeline-state, pipeline-layout - Update class overview pages to include constructor/destructor entries

RHISampler
命名空间: XCEngine::RHI
类型: class (abstract)
头文件: XCEngine/RHI/RHISampler.h
描述: GPU 纹理采样器抽象接口，用于配置纹理过滤和寻址模式。采样器定义了如何对纹理进行采样，包括过滤模式、寻址模式和各向异性级别等参数。
概述
RHISampler 是 RHI 抽象层中的纹理采样器接口，提供跨平台的纹理采样配置能力。通过 RHIDevice::CreateSampler 创建采样器实例。
关键特性:
- 支持点采样、线性采样和各向异性采样
- 支持 Wrap、Mirror、Clamp、Border 等寻址模式
- 提供原生 API 句柄访问

SamplerDesc samplerDesc;
samplerDesc.filter = static_cast<uint32_t>(FilterMode::Anisotropic);
samplerDesc.addressU = static_cast<uint32_t>(TextureAddressMode::Wrap);
samplerDesc.addressV = static_cast<uint32_t>(TextureAddressMode::Wrap);
samplerDesc.addressW = static_cast<uint32_t>(TextureAddressMode::Wrap);
samplerDesc.maxAnisotropy = 16;
samplerDesc.minLod = 0;
samplerDesc.maxLod = FLT_MAX;
RHISampler* sampler = device->CreateSampler(samplerDesc);
// 绑定到纹理单元 0
sampler->Bind(0);
// 使用完毕后关闭
sampler->Shutdown();
