PNpM CLI

Patch Changes

• 78e29fe: Prevent a crafted pnpm-lock.yaml from writing package content outside the virtual store. A dependency path key whose name reconstructs to a path-traversal sequence (e.g. ../../../tmp/x@1.0.0) is now rejected by the isolated (virtual-store) linker and the Plug'n'Play resolver map, matching the containment already applied to the hoisted linker. Under the global virtual store, a traversal in the version-derived path segment (e.g. a snapshot version: "../../x") is now rejected at iterateHashedGraphNodes, the single point every global-virtual-store slot path funnels through.
• 78e29fe: Fixed a path traversal vulnerability where a dependency whose manifest name was a scoped path traversal (e.g. @x/../../../<path>) could be written outside node_modules to an attacker-controlled location during pnpm install, even with --ignore-scripts. The isolated linker now validates the package name before using it as a directory name, matching the existing protection in the hoisted linker.
• 47ef6f0: Fixed switching to and self-updating to pnpm v12. pnpm v12 (the Rust port) ships as the pnpm and @pnpm/exe npm packages whose bins are placeholders replaced at install time by the host's native binary from a @pnpm/exe.<platform>-<arch>[-musl] optional dependency. Because pnpm installs its own engine with --ignore-scripts, that relinking never ran, leaving a non-executable placeholder. pnpm now relinks the native binary itself for v12 (recognizing the new platform-package naming scheme and the native pnpm package), and verifies the native binary's npm registry signature before running it.
• 36928be: ${...} environment-variable placeholders in the httpProxy, httpsProxy, noProxy, proxy, and noproxy settings are no longer expanded when these settings come from a project's pnpm-workspace.yaml. They now receive the same protection already applied to registry.
