/**
 * A MountResolver over a live prefix listing.
 *
 * The one concrete resolver: the workspace wraps whatever view it
 * wants a consumer to have (a sandbox-filtered list for the runtimes)
 * and the matching rule stays `ownerPrefix`'s. Reads its sources per
 * call, so mounts and links added or removed after construction are
 * always picked up.
 *
 * The link source is optional and answers nothing when absent, which
 * is right for a resolver built outside a workspace: there is no node
 * table, so no name can be a link.
