🟠 [package.json/包信息]: Missing fixed version entry / 缺少固定版本条目

English: According to RT-Thread Packages repository policy, packages should provide at least one fixed version (e.g., v1.0.0) in addition to "latest". The "site" array currently only includes "latest" pointing to the "main" branch. Please add a fixed version entry with an immutable tag or commit reference. This ensures users can select a stable, tested version.

Example format:

"site": [
  {
    "version": "v1.0.0",
    "URL": "https://github.com/GKoSon/tm1668/archive/refs/tags/v1.0.0.zip",
    "filename": "tm1668-1.0.0.zip",
    "VER_SHA": "NULL"
  },
  {
    "version": "latest",
    "URL": "https://github.com/GKoSon/tm1668.git",
    "filename": "tm1668.zip",
    "VER_SHA": "main"
  }
]

中文：根据 RT-Thread Packages 仓库规范，软件包应提供至少一个固定版本（例如 v1.0.0），而不仅仅是"latest"。当前"site"数组仅包含指向"main"分支的"latest"。请添加一个固定版本条目，使用不可变的 tag 或 commit 引用。这确保用户可以选择稳定且经过测试的版本。

🟡 [Kconfig/Kconfig]: Missing version choice for fixed version / 缺少固定版本的选项

English: The Kconfig only includes a choice for "latest" version. When a fixed version (e.g., v1.0.0) is added to package.json, you should also add a corresponding config option in the version choice section. This allows users to select the fixed version through menuconfig.

Example:

choice
    prompt "Version"
    default PKG_USING_TM1668_LATEST_VERSION
    help
        Select the package version

    config PKG_USING_TM1668_V100
        bool "v1.0.0"

    config PKG_USING_TM1668_LATEST_VERSION
        bool "latest"
endchoice

config PKG_TM1668_VER
   string
   default "v1.0.0" if PKG_USING_TM1668_V100
   default "latest" if PKG_USING_TM1668_LATEST_VERSION

中文：Kconfig 仅包含"latest"版本的选项。当在 package.json 中添加固定版本（例如 v1.0.0）后，您还应在版本选择部分添加相应的配置选项。这允许用户通过 menuconfig 选择固定版本。
