/**
 * Hierarchical project navigation by slash-path segments.
 *
 * Project names are `org/repo` (and occasionally deeper). The projects view
 * shows one path level at a time: roots first, then children under a chosen
 * prefix. A node is a leaf project when exactly one project sits at that path
 * and nothing deeper shares the prefix; otherwise it is a namespace that drills
 * down. The same factory is unit-tested in Node and interpolated into the
 * buildless dashboard client.
