// photos' events. The tool runtime imports this once the broker is bound. It watches the library and
// announces newly added assets.
//
// Emits (novox/hq ADR 0041/0042):
// module.photos.item.added — a new asset appeared in the library
//
// New assets are found by diffing the recent-assets slice by asset id. Primed silently on the first
// look, so a restart does not re-announce the whole recent list as freshly added.
