aube store prune

• Usage: aube store prune

Remove unreferenced packages from the global store.

Operates on the store printed by aube store path; it does not touch project node_modules directories, manifests, or lockfiles.

It keeps files referenced by cached package indexes and, on hardlink filesystems, files that still have project hardlink references.

On reflink filesystems such as APFS or btrfs, link counts cannot prove project reachability, so pruning relies on cached package indexes.
