New Case generates a fresh, solvable mystery via the in-process LLM (buffered one-ahead);
if generation is unavailable (no weights / load failure) it falls back to the GRAYMOOR-3107
golden case so the loop is always playable. Generated cases are persisted by Case ID, so a
shared ID reloads the identical mystery. The sealed solution is never in any response here.
