jgrusewski a4fb15fce0 diag: per-step BUFFER_DIAG — d_value_logits, d_adv_logits, grad_buf norms
Logs L2 norms of critical buffers after forward+backward+aux, before Adam.
Fires on first 3 steps of each epoch only. Identifies exactly which buffer
goes zero on H100 — is it the loss gradient or the cuBLAS backward output?
