fix(installer): reuse a standalone native pnpm such as the one mise installs - #1989
Conversation
…nstalls A Mach-O or ELF pnpm embeds its own Node runtime and has no package.json; it skips the package engine check but must still prove an exact stable version and global add/bin capability. Scripts and shims without a package still fail closed. Closes #1988.
📝 WalkthroughWalkthroughThe POSIX installer now recognizes standalone Mach-O and ELF pnpm executables. It checks their reported version and global-install capabilities without package metadata. Package-backed pnpm retains its engine and version checks; scripts and shims without a package remain unsupported. ChangesStandalone pnpm reuse

Keep package-backed native executables on the metadata check.
If a native pnpm executable has nearby pnpm package metadata, standalonePnpm(existing) still passes null to provePnpm. The installer then skips the package engine check and accepts a reported version that differs from the package version. Locate package metadata first. Skip its checks only when the metadata is absent and the executable has a recognized native header. Add a package-backed native fixture with mismatched metadata to cover this branch.
