Patch Changes

• Security fix: prevent path traversal in directories.bin field.

• When pnpm installs a file: or git: dependency, it now validates that symlinks point within the package directory. Symlinks to paths outside the package root are skipped to prevent local data from being leaked into node_modules.

  This fixes a security issue where a malicious package could create symlinks to sensitive files (e.g., /etc/passwd, ~/.ssh/id_rsa) and have their contents copied when the package is installed.

  Note: This only affects file: and git: dependencies. Registry packages (npm) have symlinks stripped during publish and are not affected.

• Fixed optional dependencies to request full metadata from the registry to get the libc field, which is required for proper platform compatibility checks #9950.
