Shared facade-level orchestration for the three spatial-index loaders
(Points / Lines / GSplats). Each helper here used to exist as three
byte-identical private methods; hoisting them keeps the facades symmetric
and unable to drift.
The loaders build ONE SpatialFacadeCtx in their constructor
(this-bound accessors over their private monitor state) and pass it to
every helper.
