Unified logging: Replace LogSystem with EditorConsoleSink

- Created EditorConsoleSink (implements ILogSink interface)
- EditorConsoleSink stores logs in memory buffer (max 1000 entries)
- Added to Debug::Logger in Application::Initialize()
- ConsolePanel now reads from EditorConsoleSink via static GetInstance()
- Removed separate LogSystem singleton
- Removed editor/src/Core/LogEntry.h (no longer needed)

Now Editor and Engine share the same Debug::Logger, with ConsolePanel
displaying logs via EditorConsoleSink.

+# RHI 模块严重问题：PipelineState 与 Shader 关系设计混乱
+
+## 问题严重程度
+
+**严重级别**: 🔴 架构级缺陷（Critical）
+
+## 问题定位
+
+根据核心设计理念：
+> - **求同存异**：优先提取 API 共性作为核心抽象
+> - **核心约束原则**：面向 D3D12/Vulkan 设计，参考 Unity RHI
+
+当前设计存在一个**根本性的架构缺陷**。
+
+## 问题详述
+
+### `RHIDevice::CreatePipelineState()` 接口设计错误
+
+```cpp
+// engine/include/XCEngine/RHI/RHIDevice.h:41
+virtual RHIPipelineState* CreatePipelineState(const GraphicsPipelineDesc& desc) = 0;
+```
+
+### `GraphicsPipelineDesc` 缺少 Shader 字段
+
+```cpp
+// engine/include/XCEngine/RHI/RHITypes.h:309-320
+struct GraphicsPipelineDesc {
+    InputLayoutDesc           inputLayout;
+    RasterizerDesc            rasterizerState;
+    BlendDesc                 blendState;
+    DepthStencilStateDesc     depthStencilState;
+    
+    uint32_t                 topologyType      = 0;
+    uint32_t                 renderTargetCount = 1;
+    uint32_t                 renderTargetFormats[8] = { 0 };
+    uint32_t                 depthStencilFormat = 0;
+    uint32_t                 sampleCount        = 1;
+    // ❌ 缺少 Shader 字段！
+};
+```
+
+## 导致的严重后果
+
+### 1. D3D12 PSO 创建后立即无效
+
+```cpp
+// engine/src/RHI/D3D12/D3D12Device.cpp:434-444
+RHIPipelineState* D3D12Device::CreatePipelineState(const GraphicsPipelineDesc& desc) {
+    auto* pso = new D3D12PipelineState(m_device.Get());
+    pso->SetInputLayout(desc.inputLayout);
+    // ... 设置各种状态
+    return pso;  // ❌ 此时 m_vsBytecode 和 m_psBytecode 都是空的！
+}
+```
+
+当调用 `EnsureValid()` 时：
+
+```cpp
+// engine/src/RHI/D3D12/D3D12PipelineState.cpp:143-146
+bool D3D12PipelineState::CreateD3D12PSO() {
+    if (!m_vsBytecode.pShaderBytecode || !m_psBytecode.pShaderBytecode) {
+        return false;  // ❌ 直接失败！
+    }
+    // ...
+}
+```
+
+### 2. 后端行为不一致，违反"求同存异"原则
+
+| 后端 | `CreatePipelineState()` 返回后 `IsValid()` |
+|------|------------------------------------------|
+| D3D12 | `false` (需要额外设置 shader) |
+| OpenGL | `true` (OpenGL 不需要预编译 PSO) |
+
+这完全违反了核心设计原则。
+
+### 3. 运行时状态污染
+
+Shader 通过 `SetShaderBytecodes()` 在运行时注入：
+
+```cpp
+// 需要外部代码手动调用
+pso->SetShaderBytecodes(vsBytecode, psBytecode);  // ❌ 语义混乱
+pso->EnsureValid();  // ❌ 现在才能创建真正的 D3D12 PSO
+```
+
+## 设计根源分析
+
+### 参考 Unity RHI 的正确做法
+
+Unity 的 `PipelineState` 是 **Shader + RenderState** 的不可变组合：
+- 创建时必须提供完整的 shader 和 state
+- 创建后不可修改
+- `IsValid()` 的语义是确定的
+
+### 当前设计的错误假设
+
+把 Shader 和 PipelineState 分离，试图让 PSO 成为"可配置的 render state 容器"，但这与 D3D12/Vulkan 的 PSO 概念完全冲突——在这些 API 中，**PSO 是 shader + state 的编译后不可变对象**。
+
+## 影响范围
+
+1. **无法正确实现 SRP**：上层渲染管线无法可靠地预编译 PSO
+2. **资源管理混乱**：PSO 何时真正创建？何时可以释放？语义不明确
+3. **测试困难**：后端行为不一致，单元测试无法统一编写
+4. **扩展性差**：未来添加 Vulkan 后端会遇到同样的问题
+
+## 建议修复方案
+
+### 方案 A：在 `GraphicsPipelineDesc` 中添加 Shader 字段
+
+```cpp
+struct GraphicsPipelineDesc {
+    // ... 现有字段
+    
+    RHIShader* vertexShader = nullptr;
+    RHIShader* pixelShader = nullptr;
+    RHIShader* geometryShader = nullptr;
+    RHIShader* hullShader = nullptr;
+    RHIShader* domainShader = nullptr;
+};
+```
+
+### 方案 B：创建专用的 ShaderProgram 类型
+
+```cpp
+struct ShaderProgramDesc {
+    RHIShader* vertexShader = nullptr;
+    RHIShader* pixelShader = nullptr;
+    // ...
+};
+
+struct GraphicsPipelineDesc {
+    ShaderProgramDesc shaders;  // 包含所有 shader
+    InputLayoutDesc inputLayout;
+    RasterizerDesc rasterizerState;
+    BlendDesc blendState;
+    DepthStencilStateDesc depthStencilState;
+    // ...
+};
+```
+
+### 方案 C：分离 PSO 创建接口
+
+```cpp
+// 独立的 Compute PSO 创建
+RHIPipelineState* CreateComputePipelineState(RHIShader* computeShader);
+
+// Graphics PSO 创建时必须提供 shader
+RHIPipelineState* CreateGraphicsPipelineState(
+    const GraphicsPipelineDesc& desc,
+    RHIShader* vertexShader,
+    RHIShader* pixelShader
+);
+```
+
+## 相关文件
+
+- `engine/include/XCEngine/RHI/RHIDevice.h`
+- `engine/include/XCEngine/RHI/RHITypes.h`

+- `engine/src/RHI/OpenGL/OpenGLDevice.cpp`
+
+## 总结
+
+**`GraphicsPipelineDesc` 缺少 Shader 字段** 导致：
+
+1. 抽象层无法正确表达 D3D12/Vulkan 的 PSO 概念
+2. 后端行为不一致，违反"求同存异"
+3. PSO 生命周期管理语义混乱
+
+这是整个 RHI 模块**最严重的架构级缺陷**，应该优先修复。
