/**
 * Mirrors the loaded models into `BimState.modelIds`.
 *
 * `modelIds` existed on the store from the start but nothing ever wrote to it, so
 * it was permanently `[]` — anything deriving from it concluded no model was
 * loaded even with one on screen. `FragmentsManager.list` is the truth; this
 * publishes it.
 *
 * One central subscription, the same shape as `SelectionSync` and
 * `ShadowEnroller`, so every load path is covered rather than each caller wiring
 * its own listener. `IfcClasses` already subscribes to the
 * same two events to rebuild its class tree.
 *
 * Renders nothing. Mount it once inside the BIM viewer.
