  1. feat: add mcpplibs-xpkg 0.0.57, capi-lua 0.0.3, tinyhttps 0.2.9 

    三个包的最新版本此前都停在索引里够不到的位置:xpkg 0.0.41、capi-lua 0.0.2、
tinyhttps 0.2.3。用 xmake 构建任何依赖这些库当前版本的工程,都会停在

    error: package(mcpplibs-xpkg): no available schemes with urls and versions

**mcpplibs-xpkg 还需要索引替它提供构建描述。** 0.0.42 起 libxpkg 迁到了 mcpp,
tarball 里是 `mcpp.toml` + `build.mcpp`,**一个 xmake.lua 都没有** —— 于是
`package.tools.xmake` 无从下手。所以 `on_install` 在检测到没有 xmake.lua 时写一份
再构建;老版本自带描述,那条路径原样不动。

新版的目录也扁平化了:五个模块直接在 `src/` 下,不再是一个模块一个目录,因此
补出来的描述是**一个** static target,而不是老版的五个。

`mcpplibs.xpkg.lua_stdlib` 仍然是生成的(把 `src/lua-stdlib` 下每个 .lua 嵌成
一个 string_view)。两个细节是从踩坑里来的:

* 生成物写进 `src/`,让已有的 `src/*.cppm` glob 覆盖它。写到别处再事后
  `add_files` 会晚于模块扫描建立 provider 表,构建随后报
  `missing mcpplibs.xpkg.lua_stdlib dependency` —— 指着消费者,不提生成物。
* .lua 清单用 **glob 而不是手抄**。0.0.41 嵌 10 个文件,0.0.57 是 11 个
  (`xim/libxpkg/subos.lua` 是新增的),抄一份就会静默漏掉它,并在三个文件之外
  的消费者里炸。排序保证输出逐字节可复现。

  2. fix(cmdline): install the library target only 

    `import("package.tools.xmake").install(package)` 不限定 target,于是把工程的
examples 和 tests 一起编 —— 而 cmdline 的 xmake.lua 在 macOS 以外都
`includes("examples", "tests")`。结果是任何没有预装 gtest 的机器上安装都会死在

    tests/cmdline_test.cpp:1:10: fatal error: gtest/gtest.h: No such file or directory

索引里其他包(capi-lua、tinyhttps、xpkg)本来就都限定了 target,只有这个漏了。

  3. fix(mcpplibs-xpkg): accept libxpkg's un-prefixed tags 

    libxpkg 的 tag 命名在 0.0.42 前后变了:0.0.41 及更早是 `v0.0.41`,0.0.57 是
`0.0.57`(没有 `v`)。包里只有带 `v` 的模板,于是新版本根本下不下来:

    we can also download these packages manually:
      - https://github.com/openxlings/libxpkg/archive/refs/tags/v0.0.57.tar.gz

实测 `v0.0.57` 是 404、`0.0.57` 是 200。两种拼法都列上,xmake 按顺序尝试,
404 的那条不花代价。sha256 本来就是按无前缀那个 tarball 算的,不用动。
