Bump MLX to the latest selected upstream ref and update the MLX/imagegen wrappers and tests for the new API behavior. Fix the CUDA MLX archive so runtime NVRTC kernels work after deployment: package CUTE/CUTLASS headers, include the CUDA runtime header closure, and stage a coherent CUDA-toolkit-matched CCCL tree instead of MLX's fetched CCCL for CUDA payloads. The previous archive could build successfully but crash at runtime due to missing or incompatible JIT headers.
