feat(cli): sort global package list output (#1748)

The current `vp list -g` output depends on filesystem directory
iteration order, so global packages can be printed in a random order.

This PR sorts global package metadata by package identity before
returning it from `PackageMetadata::list_all()`. That makes global pm
commands like `vp list -g` follow `npm list -g`'s alphabetical package
tree ordering for both human-readable and JSON output.
