* fix(installation): skip pnpm exe when no Node.js is on PATH
When pnpm is installed as @pnpm/exe (a Single Executable Application
that bundles Node.js into the pnpm binary) and the user has no separate
Node.js on PATH, `which('node')` fails and `getNodeExecPath` used to
fall back to `process.execPath` - which in @pnpm/exe is the pnpm binary
itself, not a Node binary. That path got baked into generated global
bin shims via nodeExecPath, so running any globally-installed CLI
invoked pnpm with the target script as its first positional arg,
producing `ERR_PNPM_NO_IMPORTER_MANIFEST_FOUND` from the current
working directory.
Detect the @pnpm/exe case via `detectIfCurrentPkgIsExecutable` and
return undefined from the fallback so the shim emits a plain
`exec node <target>` instead.
