This PR implements
expected_input_specsupport in the MLXLambdalayer to match the JAX implementation. Previously,expected_input_specwas accepted inLambda.Configfor compatibility but was completely ignored by the MLX runtime.The MLX dynamic shape probing (
_probe_output) currently supports ainput_dtypeargument, but it is ignored byget_output_shape, which assumesmx.float32. Theinput_dtypeargument is now overwritten by the config'sexpected_input_spec.
