Cast Model Merger GUI v2.4.3

眼球被遮罩误伤修复

• 数据核查发现：眼睛材质的语义 4a 贴图是平滑渐变（阴影类数据），并非发片/泪线那样的剪影遮罩——把它当覆盖率抖动会抹掉约七成眼球，看起来像闭眼。现在只有源项目 profiles.json 中声明 requires: ["opacity"] 的发片与泪线应用 4a 遮罩，眼球恢复完全不透明渲染，与源项目一致。

The eye material's semantic-4a texture turned out to be a smooth gradient (shadow data), not the bimodal coverage silhouette that hair cards and the tearline carry — dithering the eyeball with it erased most of the eye. Only the profiles that declare requires: ["opacity"] in the shader project (hair_card, tearline) now apply the 4a mask; the eyeball renders fully opaque again, matching the source project.

• 发布包精简：ZIP 现在只包含主程序 CastModelMerger.exe 与中英文使用指南（docs/user-guide.zh-CN.md、docs/user-guide.en.md），不再附带 README、截图与第三方声明。

The release ZIP now ships only the executable and the bilingual user guides.

解压 ZIP 后运行 CastModelMerger.exe，无需安装 .NET 或 Rust。Extract the ZIP and run CastModelMerger.exe; no .NET or Rust installation required.
