Method dispatch

native/shared/src/renderer/material_system.rs:1557–1565

Dispatch all queued material draws. Caller owns the render pass; this method binds the pipelines + groups + meshes and issues indexed draws. `mesh_fetch` is a closure that returns `(vertex_buffer, index_buffer, index_count)` for a given (mesh_handle, mesh_idx) — lets the renderer hand over its `model_gpu_cache` without this module taking a dependency on it.
