在这里说一声抱歉，在未经过沟通的情况下就在 Github 上开 PR，但因为种种原因（Gitlab 送中），我无法登入 Gitlab，而国内版的极狐又无法搜索到您的项目，所以才选择在 Github 上进行贡献

由于整合包不再将 Radiance 本体打包至整合包，且 DLSS 是在安装时进行下载的，而不是打包进整合包内，理论上是不会有许可证问题的，所以应该是可以上传到 Modrinth 的。但是呢建议给整合包选择一个许可证，例如 MIT

Copilot's summary

This pull request introduces a major update to the build process and packaging for the project, adding support for platform-specific (Windows and Linux) Modrinth packs. It restructures how the modpacks are assembled, updates dependencies, and includes new mod files for each platform.

Platform-specific packaging and build process:

• Added new template files for Windows (mrpack_windows.template.json) and Linux (mrpack_linux.template.json) modpacks, each referencing the correct DLSS library versions and file hashes for their respective platforms. The server environment is now marked as "unsupported" for these libraries. [1] [2]
• Updated the build script (build.lvt) to generate separate modpack files for Windows and Linux, using the new templates and including platform-specific mods from src/mods-windows and src/mods-linux. The output files are now clearly named for each platform, and the process ensures the correct icon and metadata are included.

Mod and dependency updates:

• Added new mod metadata files for the Linux (Radiance-0.1.4-alpha-fabric-1.21.4-linux.jar.mrf) and Windows (Radiance-0.1.4-alpha-fabric-1.21.4-windows.jar.mrf) versions of the Radiance mod, each with its own version ID and SHA1 hash. [1] [2]
• Updated modmenu to version 13.0.4, including a new SHA1 hash, and renamed the metadata file accordingly.

Cleanup and versioning:

• Removed the old, generic mrpack.template.json file, as it has been replaced by platform-specific templates.
• Bumped the project version from A0.13 to A0.14 in proj.json to reflect these significant changes.
