fix: improve doc link navigation and tree display

- Fix link resolution with proper relative/absolute path handling
- Improve link styling with underline decoration
- Hide leaf nodes from tree, only show directories
- Fix log file path for packaged app

+# Quaternion::FromEulerAngles
+
+```cpp
+static Quaternion FromEulerAngles(float pitch, float yaw, float roll)
+static Quaternion FromEulerAngles(const Vector3& euler)
+```
+
+从欧拉角创建四元数。角度以弧度为单位。
+
+**参数：**
+- `pitch` - 俯仰角（X 轴旋转）
+- `yaw` - 偏航角（Y 轴旋转）
+- `roll` - 翻滚角（Z 轴旋转）
+- `euler` - 欧拉角向量 (pitch, yaw, roll)
+
+**返回：** `Quaternion` - 表示旋转的四元数
+
+**复杂度：** O(1)
+
+**示例：**
+
+```cpp
+Quaternion rot = Quaternion::FromEulerAngles(0.0f, 90.0f * DEG_TO_RAD, 0.0f);
+Quaternion rot2 = Quaternion::FromEulerAngles(Vector3(0.0f, 90.0f * DEG_TO_RAD, 0.0f));
+```
