Create an empty mesh node — a THREE.Mesh with a one-vertex degenerate geometry,
attached before any data is fetched.
Same contract as the sibling createEmptyXNode factories: the commit path finds
this object by name and populates it, so an initial-load failure leaves a
recoverable scene state rather than a hole, and a later retry has somewhere to
write. The geometry is replaced in place on first commit.
