Expand description

Build the three Arrow tables (mesh metadata / vertices / indices) for a slice of meshes under plan. base_vertex_offset / base_index_offset seed the mesh-table vertex_start / index_start columns so an incremental caller (the streaming cache writer) emits GLOBAL whole-model offsets while the per-batch client blobs keep batch-local ones (bases 0/0). The Z-up to Y-up transform lives here, in one place, for both paths.
