Listener bookkeeping for the spatial-index loader's monitor surface,
shared across the points / lines / gsplats facades.
Originally lived in data/points/; hoisted to data/loaders/ once
lines and gsplats grew the same monitor surface. The subscribe /
unsubscribe / fan-out behavior — including the try/catch shielding
that prevents one bad listener from blocking the rest — is
unit-tested in isolation, without a zarr store or an active query
map.
