pnpm cache path

添加于：v11.22.0

打印 pnpm 用于元数据缓存的目录，与 pnpm store path 对应。输出的路径是绝对路径且经过了词法清理，因此使用相对路径配置 cacheDir 也能生成可供其他工具使用的路径。

pnpm cache path

pnpm 根据平台和 cacheDir 设置来确定该目录，因此，想要缓存该目录的 CI 配置无需再手动复刻这一解析逻辑：

- name: 获取缓存目录
  run: echo "PNPM_CACHE_DIR=$(pnpm cache path)" >> $GITHUB_ENV

Besides registry metadata and the pnpm dlx cache, that directory holds the lockfile verification log: the record of which lockfile passed which supply-chain policies. Restoring it lets a job skip re-verifying a lockfile the log already covers under the policies currently configured. That check is the dominant cost of an install in CI once the store is warm. 从 v11.22.0 开始，pnpm store prune 不再删除该日志。
