Documents the gotcha where convert_hf_to_gguf.py crashes with
'config.json not found' because the training output directory holds

save_pretrained_merged() fix snippet, verification checklist, and
resume-pipeline-without-retraining pattern.
Discovered today during the MajorTwin v8c pipeline failure (Step 4).
