I noticed in your generateA method for ML-KEM, that you allocate your 3-dim array as ` short[][][] a = new short[mlKem_k][mlKem_k][];`  Since you're going to effectively return all those 3rd dimension arrays you initially allocated back to the GC once you've assigned them all down on line 869, could you do the same thing here?
