20 professions now cross-referenced by state

We doubled the profession × state corpus to 20 professions × 51 jurisdictions — 1,020 pages total. The new 10: dentists, pharmacists, architects, psychologists, airline pilots, electricians, plumbers, police officers, journalists, financial analysts. Alongside this, we rebuilt the internal linking graph: every state page now lists its profession and field variants; every profession-state page cross-navigates to other professions in the state and the same profession in neighboring states. Link density matters for discovery; that's the investment.
