Add AI Laws by State (50-state AI legislation tracker)

[ailawsbystate]

This adds AI Laws by State, a free 50-state tracker for U.S. AI legislation that covers:

• Bill status, effective dates, and penalty structures across all 50 states
• Topic-specific trackers (deepfakes, hiring, healthcare AI, disclosure, bias audits)
• Primary-source linked — every entry cites the official state legislature URL
• Free tier covers state pages, bill detail, and basic search; Pro tier for CSV exports, alerts, comparison tools, and full historical data

Fits in the United States of America section under Regulation and Policy because it is a comprehensive open tracker for state-level AI legislation — a resource practitioners, researchers, and policymakers working on U.S. AI regulation will find valuable.
