fix(consult): card carries the engine's short Narayana label; AD/PD drop derivable years (BUG-1215)

The full note pushed steve_jobs/marriage to 12,028 characters (budget
12,000), and cutting it in the card broke the 'nothing rewritten' contract.
The engine now also writes algorithm_label 旧算法（从上升起、一律顺行）, the card
copies it verbatim, and Narayana AD/PD rows drop years (end_age - start_age).
Largest card 11,979 (baseline 11,983). Goldens re-captured; the biography
golden now keeps the Narayana label keys too.
