feat(文件列表): 增强list命令功能并更新文档

- 为list命令添加详细模式(-l参数)，显示文件大小和类型信息
- 改进文件列表显示格式，添加标题、分隔线和统计信息
- 根据文件类型和扩展名显示不同颜色
- 更新README.md中的安装说明
- 将bios.lua中的reboot重命名为restart以保持一致性

+wget run https://gh.catmak.name/https://raw.githubusercontent.com/Leonmmcoset/LeonOS/refs/heads/main/install.lua
-LeonOS is a reimplementation of [CC: Tweaked](https://github.com/CC-Tweaked/CC-Tweaked)'s LeonOS, intended to be cleaner and easier than the original LeonOS.
+```
-
+to install the LeonOS system.
-Key changes:
-
- - No. More. CCPL!!
- - All previously global APIs (with the exception of the standard Lua ones) have been removed.
- - Non-standard `os` API functions are now in the `rc` table, e.g. `os.sleep` becomes `rc.sleep` or `os.pullEvent` becomes `rc.pullEvent`.
- - Native support for proper thread management (`parallel` implementation builds on this)
- - Multishell works even on standard computers, and is navigable with keyboard shortcuts!
-
-See [the LeonOS website](https://ocaweso.me/LeonOS) for more details.
