[Enhancement] 导出整合包-文件选择优化

[ToobLac]

• 隐藏版本根目录下 natives-os-arch 文件夹
• 将文件/文件夹名称放到注释前面
• 排序时将目录放在前面，按名称排序
• 修复 Windows 上排除不正确的问题

Resolves #6073 Fixes #6116

顺带提一句，电磁炉在 #5367 中的修复是没有问题的，因为所谓“其他地方”都不会传入目录，不会被他的修改影响到。

Code Review

This pull request refactors the modpack file selection UI and filtering logic, introducing a directory-first sorting mechanism and hierarchical level tracking. However, several issues were identified: setting CheckBoxTreeItem values to empty strings breaks file path construction in the export logic, and the use of substringAfter for labels displays incorrect nested paths. Additionally, performing I/O operations like Files.isDirectory inside a comparator significantly impacts performance, and a redundant match method was introduced in the Modpack class that duplicates existing logic in ModAdviser.

Code Review

This pull request refactors the modpack file selection UI by introducing a custom ModpackFileTreeItem and enhancing the tree's filtering and sorting logic. It also standardizes path handling to use forward slashes for cross-platform consistency and moves matching logic into the Modpack class. Feedback suggests implementing case-insensitive sorting for the file tree to improve the user experience on Linux and optimizing regex matching in Modpack by pre-compiling patterns to avoid performance issues during large file processing.
