ssdfasd b414bc5326 refactor(docs): Fix broken links across multiple modules
Fixed broken references:
- texture-import-settings: Fix 16 files referencing wrong overview filename
- math/rectint: Fix 9 method links (rectint-* → get*, contains, intersects)
- rhi/opengl/device: Fix 8 cross-references (opengl-* → */**)
- resources/mesh: Fix meshsection and vertexattribute links
- rhi/d3d12/sampler: Fix RHISampler reference path
- math/vector3: Fix projectonplane → project-on-plane
- rhi/opengl/command-list: Remove broken ClearFlag enum ref
- rhi/opengl/device: Create 2 new method docs (MakeContextCurrent, GetNativeContext)
- rhi/device: Fix device-info types reference

All 0 broken references remaining.

# Ray::Intersects (plane)
```cpp
bool Intersects(const Plane& plane, float& t) const
```
检测射线是否与平面相交。通过计算射线与平面法线的点积判断平行,通过求交公式计算交点。
**参数:**
- `plane` - 要检测的平面
- `t` - 输出交点的参数距离(仅在返回 true 时有效)
**返回:** `bool` - 相交返回 truet >= 0否则返回 false
**线程安全:**
**复杂度:** O(1)
**异常:**
**示例:**
```cpp
#include <XCEngine/Core/Math/Ray.h>
#include <XCEngine/Core/Math/Plane.h>
#include <XCEngine/Core/Math/Vector3.h>
using namespace XCEngine::Math;
Ray ray(Vector3(0.0f, 1.0f, 0.0f), Vector3(0.0f, -1.0f, 0.0f));
Plane groundPlane(Vector3(0.0f, 1.0f, 0.0f), 0.0f);
float t;
if (ray.Intersects(groundPlane, t)) {
Vector3 hitPoint = ray.GetPoint(t);
}
```
